Population Genetic Characteristics of the D1S80 locus in seven human populations

We have analyzed the allele frequency distribution at the highly polymorphic variable number of tandem repeat (VNTR) locus D1S80 (pMCT118) in seven ethnic populations (namely, New Guinea Highlanders of Papua New Guinea, Dogrib Indians of Canada, Pehuenche Indians of Chile, American and Western Samoans, Kacharis of Northeast India, and German Caucasians) using the polymerase chain reaction (PCR) technique. In the pooled sample of 443 unrelated individuals 20 segregating alleles were detected. A trimodal pattern of allelic distribution is present in the majority of populations and is indicative of the evolutionary antiquity of the polymorphism at this locus. In spite of the observed high degree of polymorphism (expected heterozygosity 56%–86%), with a single exception — the marginally significant P value (0.04) of the exact test in American Samoans — the genotype distributions in all populations conform to their respective Hardy-Weinberg expectations. Summary statistics indicate that, in general, the allele frequency distribution at this locus may be approximated by the infinite allele model. The data also demonstrate that alleles that are shared by all populations have the highest average frequency within populations. Furthermore, the kinship bioassay analysis demonstrates that the extensive variation observed at the D1S80 locus is at the interindividual within population level, which dwarfs any interpopulation allele frequency variation, consistent with the population dynamics of hypervariable polymorphisms. These characteristics of the D1S80 locus make it a very useful marker for population genetic research, genetic linkage studies, forensic identification of individuals, and for determination of biological relatedness of individuals.     

A population genetic study of six VNTR loci in three ethnically defined populations.

To investigate the population genetic characteristics of VNTR polymorphisms in human populations, we have studied the allele frequency distribution of six VNTR loci (D1S57, RB1, D1S77, D1S61, alpha-globin 5'HVR, D1S76) in three well-defined populations (Kachari of Northeast India; Dogrib Indian of Canada; and New Guinea Highlander of Papua New Guinea). Even though the number of alleles sampled is limited, 48 to 92 alleles per locus per population, significant variation is noticed in the number of alleles per locus for all the populations. Using alternate summary measures, we have observed that genotype distributions at the six VNTR loci apparently conform to their respective Hardy-Weinberg predictions. Multilocus genotype profiles of the individuals in each of the three populations suggest that the VNTR alleles are independently segregating with the exception of the two linked loci D1S76 and D1S77. Lack of fit of all VNTR loci to one particular model of mutational change, either the Infinite Allele Model or the Stepwise Mutation Model, suggests more than one mechanism for production of new VNTR alleles. This study also indicates that increased heterozygosity at VNTR loci in comparison to protein and blood group loci may lead to more accurate estimates of genetic distance.     

The relevance of paternity analysis in Romanian population using the D1S80 locus

At present, DNA fingerprinting for human identification and paternity testing is a necessary and usual procedure. D1S80 is one of the best known polymorphic loci showing a VNTR, and exhibiting a high heterozygosity. This genetic locus, with a Tsp 509 I polymorphism of its 5' flanking sequence (1, 9), have been successfully amplified from human genomic DNA isolated from blood. The Tsp 509 I polymorphism was detected by restriction after PCR amplification. We tested the relevance of paternity analysis using the D1S80 locus considering the allele frequency distribution characteristic for our country. Paternal and maternal bands were compared with the children's DNA patterns. Our data include a comparison between D1S80 alleles amplified from mother, child and the supposed father for three tested families. This study was the first of this type made in Romania. We concluded a good power of discrimination and exclusion for this locus. It can be used successfully in the case of subtypes with low frequencies, and this is frequent for our population because of the high heterozygosity of D1S80 subtypes in Romanian population. We recommend the D1S80 use for exclusion paternity tests in Romanian population, as a very useful molecular tool, but we also recommend a complete set of molecular markers for confirmation paternity test in the same population.     

Genetic quality of the Miyaluo captive forest musk deer (Moschus berezovskii) population as assessed by microsatellite loci

The Miyaluo captive forest musk deer population (Sichuan Province, China) is one of the largest captive breeding populations in the world. In order to evaluate the genetic quality and provide available genetic management strategy, seven polymorphism microsatellite loci were applied to assess the genetic variation of the Miyaluo forest musk deer. The results indicated that a total of 168 alleles were detected from these seven microsatellite loci in 361 individuals, and the number of the alleles per locus ranged from 12 to 41 with a mean of 24. The average observed heterozygosity, expected heterozygosity, and PIC were 0.782, 0.854, and 0.837, respectively. Considering the results of the loci Hardy–Weinberg equilibrium test, the comparison of the common allele frequency as well as the private allele between the adults and juveniles, we concluded that the heterozygosity and the genetic diversity of the Miyaluo captive breeding population are increasing due to the input of new individuals from other populations. However, the frequency of some alleles declined sharply, and some were even lost indicating that there is a risk for diversity loss. Thus, we proposed an improved management and breeding strategy for the captive breeding population of the forest musk deer.     

PCR amplification of alleles at the DIS80 locus: comparison of a Finnish and a North American Caucasian population sample, and forensic casework evaluation.

Allele and genotype frequencies for the highly polymorphic D1S80 locus were determined in a Finnish population sample by using PCR followed by high-resolution PAGE and silver staining, a procedure called the amplified-fragment-length polymorphism (Amp-FLP) technique. In 140 unrelated Finnish individuals 15 alleles and 43 phenotypes were observed. The D1S80 locus demonstrated a heterozygosity of .77, and the power of discrimination was .92 in this sample representing a genetically isolated Finnish population. The distribution of observed genotypes conformed to Hardy-Weinberg expectations. In 36 mother-child pairs Mendelian inheritance for the alleles at the D1S80 locus could be demonstrated in all cases, and no mutations were observed. The usefulness of the D1S80 locus for forensic casework was assessed by using Amp-FLP analysis of the D1S80 locus in 36 forensic cases including 18 rapes, 14 homicides, and 4 other violent crimes. In most cases valuable information was obtained using the Amp-FLP technique, and in no case was there indication of either false-positive or false-negative results.     

Allele frequency of VNTR locus D1S80 observed in Hb D-Los Angeles carrires

One of our previous studies presented the allele frequencies of D1S80 VNTR locus in province Denizli including the high frequencies of allele 24 and 18. In Denizli province of Turkey, the most common abnormal variant is Hb D-Los Angeles with a frequency of 57.8?% of the total abnormal Hbs. The aim of this study is to identify the allele frequencies of D1S80 VNTR locus in Hb D-Los Angeles carriers in Denizli province of Turkey. We studied unrelated 36 Hb D-Los Angeles carriers residing in Denizli province of Turkey. The size range of the D1S80 VNTR locus PCR products was determined first by agarose gel electrophoresis and then by a capillary electrophoresis system. For all subjects, DNA sequencing was performed. Allele frequency, theta (k) value, and observed and expected heterozygosity were calculated using Arlequin Software version 3.11. The most common alleles were the 24 (32?%), 18 (18.1?%) and 29 (16.7?%) alleles, and frequencies of these alleles were 0.329, 0.186 and 0.171 respectively. Other observed alleles percentages were 33, 2?%. We did not observe alleles 6, 15, 27 and 35, but we observed alleles 20 and 33. Results were in Hardy–Weinberg linkage disequilibrium. Observed heterozygosity was 0.889, and expected heterozygosity was 0.847. Theta (k) value was 4.91 (95?% confidence interval limits). According to our results, we concluded that Hb D-Los Angeles carriers have different allele frequencies in D1S80 VNTR and also have their own D1S80 VNTR locus divergence.     

Analysis of the VNTR locus D1S80 by the PCR followed by high-resolution PAGE.

Allelic data for the D1S80 locus was obtained by using the PCR and subsequent analysis with a high-resolution, horizontal PAGE technique and silver staining. Compared with RFLP analysis of VNTR loci by Southern blotting, the approach described in this paper offers certain advantages: (1) discrete allele resolution, (2) minimal measurement error, (3) correct genotyping of single-band VNTR patterns, (4) a nonisotopic assay, (5) a permanent record of the electrophoretic separation, and (6) reduced assay time. In a sample of 99 unrelated Caucasians, the D1S80 locus demonstrated a heterozygosity of 80.8% with 37 phenotypes and 16 alleles. The distribution of genotypes is in agreement with expected values according to the Hardy-Weinberg equilibrium. Furthermore, the observed number of alleles and the level of heterozygosity, obtained through the protocol described here, were congruent with each other in accordance with the expectation of a mutation-drift equilibrium model for a single, homogeneous, random-mating population. Therefore, the analysis of D1S80 and similar VNTR loci by amplified fragment length polymorphism (AMP-FLP) may prove useful as models for population genetic issues for VNTR loci analyzed by RFLP typing via Southern blotting.     

Polymorphism of trinucleotide repeats at loci FRAXA and FRAXE in the population of Tomsk

Polymorphism of CGG and GCC trinucleotide repeats, whose expansions at the FRAXA and FRAXE loci have been identified as causative mutations in two forms of mental retardation, was studied in Slavic population of Tomsk. At the FRAXA locus a total of 31 allelic variants ranging from 8 to 56 copies of CGG repeat with two modal classes of 28-29 and 18-20 repeat units (with the frequencies of 24.6 and 11.5% respectively) were revealed. Compared to other populations, this locus was characterized by unusually high frequency of intermediate alleles with the sizes of more than 40 CGG repeat units (12.4%). Since intermediate repeats of the FRAXA locus were more prone to instability than normal alleles, it was suggested that Slavic population of Siberia had higher risk of the development of FMR1 dynamic mutations, giving rise to the Martin-Bell syndrome. The FRAXE allele frequency distribution was demonstrated to be normal with 18 allelic variants ranging from 9 to 27 GCC repeat units. In the population of Tomsk this locus had higher than in other populations frequency (26.7%) of short (less than 15 repeat units in size) alleles. In addition, in the Tomsk population both loci were characterized by high level of heterozygosity and low frequencies of modal allele classes. These results can be explained by the high level of outbreeding typical of the population of Siberia.     

Genetic variation among four Mexican populations (Huichol, Purepecha, Tarahumara, and Mestizo) revealed by two VNTRs and four STRs

Allele distributions of two polymorphisms with variable number of tandem repeats (VNTR), D1S80 and APOB, and four polymorphisms with short tandem repeats (STR), VWA, TH01, CSF1PO, and HPRTB, were analyzed in three Mexican ethnic groups: Huichol, Purepecha, and Tarahumara. Genotype distribution was in agreement with Hardy-Weinberg expectations for each locus and ethnic group. Heterozygosity (H), power of discrimination, and probability of exclusion were estimated. The three groups presented some distinctive genetic features: (1) a diminished genetic diversity (H = 66.8% to 73.4%) and mean number of alleles by locus (5.8 to 6.3) in comparison with Mexican mestizos (H = 78.3%, 10.5 alleles/locus), and (2) uneven allele distributions as evidenced by "distinctive alleles" with high frequencies, especially in the Tarahumara and the Huichol. Genetic relatedness analysis included data from a previously typed mestizo population, the largest and most widely distributed population in Mexico. Allele distribution differentiation was observed among all four groups, except between mestizo and Purepecha (p > 0.05), which was interpreted as indicating a larger Spanish component in the Purepecha as a result of gene flow effects. Although intrapopulation inbreeding (FIS) was not significant, heterozygote deficiency in the total population (FIT) and divergence among populations (FST) were significant (p < 0.05). Genetic distances displayed a closer relationship among mestizos, Purepechas, and Huichols in relation to Tarahumaras. Correlation between the observed genetic features and the geographic isolation level points to genetic drift as the main cause of differentiation among these Mexican populations.     

Polymorphism of trinucleotide CAG-repeats of the first exon of the androgen receptor gene in the Tomsk population

Polymorphism of the CAG repeat of exon 1 of the androgen receptor (AR) gene was analyzed in the Tomsk population. In total, 12 alleles varying in size from 285 to 318 bp (21-32 CAG units) were revealed. The allele frequency distribution did not differ from the normal one. No difference in allele frequencies was detected between men and women of the same generation. The observed heterozygosity was equal to the expected one (0.88 +/- 0.03). Compared with other populations, the Tomsk population displayed a narrower allele spectrum and a bias of the most common allele to a greater repeat number. The results obtained may reflect specific population genetic processes characteristic of young developing populations.     

Short tandem repeat polymorphism of the D2S1242 locus in a Japanese population

Allele frequencies and sequence characteristics of the D2S1242 short tandem repeat (STR) locus were studied in a Japanese population sample. A total of 10 D2S1242 alleles and 34 genotypes were identified in 273 unrelated Japanese individuals. The five most common alleles detected had frequencies of over 10%. No deviations from Hardy-Weinberg equilibrium were found when the expected allele values were compared with the observed values. Sequence analysis of each allele showed a tetranucleotide polymorphism. Alleles 9 to 14 had different sequence structures than alleles 15 to 19. Allele 18 had a different sequence in the Japanese sample compared to an Austrian sample. The power of discrimination was 0.95. The present results demonstrate that the D2S1242 STR locus is a useful genetic marker in the Japanese population.     

Short alleles revealed by PCR demonstrate no heterozygote deficiency at minisatellite loci D1S7, D7S21, and D12S11.

Short VNTR alleles that go undetected after conventional Southern blot hybridization may constitute an alternative explanation for the heterozygosity deficiency observed at some minisatellite loci. To examine this hypothesis, we have employed a screening procedure based on PCR amplification of those individuals classified as homozygotes in our databases for the loci D1S7, D7S21, and D12S11. The results obtained indicate that the frequency of these short alleles is related to the heterozygosity deficiency observed. For the most polymorphic locus, D1S7, approximately 60% of those individuals previously classified as homozygotes were in fact heterozygotes for a short allele. After the inclusion of these new alleles, the agreement between observed and expected heterozygosity, along with other statistical tests employed, provide additional evidence for lack of population substructuring. Comparisons of allele frequency distributions reveal greater differences between racial groups than between closely related populations.     

The spectrum of microsatellite loci on chromosomes 7 and 8 in Taiwan aboriginal populations: a comparative population genetic study

Sixteen microsatellite loci on chromosomes 7 and 8 of Han-Taiwanese and six Taiwan aboriginal populations were systematically analyzed by a high-resolution multiple-fluorescence-based polymerase chain reaction technique. Analysis of allele frequency distribution indicated the genetic divergence among these populations. Several alleles were unique to specific tribes. Only the D8S556 locus deviated from Hardy-Weinberg equilibrium in all tribes. Its F_IS level, as calculated with the Nei method, was also higher and more homozygous than expected. Therefore, with the exception of D8S556, these variable number of tandem repeats (VNTR) loci are suitable genetic markers for forensic and paternal testing. The F_ST level, as the proportion of the total variation among these tribes, ranged from 1.4% at the D7S484 locus to 6.8% at the D7S550 locus. The average F_ST was 3.9%, suggesting that there were substantial variations among these populations. The genetic identity analysis and the genetic distance analysis reached the same conclusions, viz., that the Ami and the Paiwan tribes were genetically close to each other, that the Atayal tribe was relatively unique compared with other tribes, and that the Saisiat tribe was relatively close to the Han-Taiwanese. A dendrogram for these tribes was further constructed by the UPGMA method. These VNTR data not only facilitate forensic and paternity testing, but also provide anthropometric information for further elucidating the relationship of Taiwan populations to the Austronesian family.

Characteristics of polymorphism at a VNTR locus 3' to the apolipoprotein B gene in five human populations.

We have analyzed the allele frequency distribution at the hypervariable locus 3' to the apolipoprotein B gene (ApoB 3' VNTR) in five well-defined human populations (Kacharis of northeast India, New Guinea Highlanders of Papua New Guinea, Dogrib Indians of Canada, Pehuenche Indians of Chile, and a relatively homogeneous Caucasian population of northern German extraction) by using the PCR technique. A total of 12 segregating alleles were detected in the pooled sample of 319 individuals. A fairly consistent bimodal pattern of allele frequency distribution, apparent in most of these geographically and genetically diverse populations, suggests that the ApoB 3' VNTR polymorphism predates the geographic dispersal of ancestral human populations. In spite of the observed high degree of polymorphism at this locus (expected heterozygosity levels 55%-78%), the genotype distributions in all populations (irrespective of their tribal or cosmopolitan nature) conform to their respective Hardy-Weinberg predictions. Furthermore, analysis of the congruence between expected heterozygosity and the observed number of alleles reveals that, in general, the allele frequency distributions at this locus are in agreement with the predictions of the classical mutation-drift models. The data also show that alleles that are shared by all populations have the highest average frequency within populations. These findings demonstrate the potential utility of highly informative hypervariable loci such as the ApoB 3' VNTR locus in population genetic research, as well as in forensic medicine and determination of biological relatedness of individuals.     

Molecular genetic diversity in 5 populations of Madhya Pradesh, India

This paper presents data on the distribution of 3 amplified fragment length polymorphisms (D1S80, APOB, and YNZ22) in 5 populations of Central India. Using the polymerase chain reaction technique, 3 caste (Brahmin, Khatri, and Dhimer) and 2 tribal (Gond and Baiga) populations were studied for the 3 loci. The allelic variations observed in the caste populations are compatible with those of many Caucasian populations, but the caste populations showed significant overall and interpopulation variability within the region. D1S80 allele *24 varied from 32% (Dhimers) to 42% (Brahmins). Allele *18 was not observed in Baiga tribal populations, but in caste populations it varied from 11% (Dhimers) to 24% (Brahmins). Both tribal populations showed higher frequencies of allele *31 (17%-18%). For APOB, caste populations again showed bimodal distribution of alleles *35 and *37, but in tribal populations higher allele numbers (*47, *49) were also frequent. For YNZ22, extensive variation was observed for all populations studied. Allele *4 was the most common in caste populations, while alleles *2, *7, and *10 were prominent in tribal populations. The level of gene differentiation is not very high for the 3 systems studied in the 5 populations. Overall, allele frequency distribution, heterozygosity, and genetic diversity analysis show that the genetic diversity observed is socially and geographically structured.     

Analysis of polymorphism of CTG repetitive sequences in the gene of myotonic dystrophy in human populations of the Volga-Ural region]

Distribution of CTG repetitive sequences in the myotonic dystrophy (MD) gene was analyzed in ten populations of the Volga-Ural region, including Tatars, Chuvashes, Maris, Udmurts, Mordovians, Komis, and four ethnogeographical groups of Bashkirs. A total of 25 alleles were found (9 to 14 in individual populations), with each allele containing 5 to 34 trinucleotide repeats. The allele frequency distribution had two peaks corresponding to alleles with 5 and 11-14 CTG repeats. The frequency of the (CTG)5 allele varied from 0.23 to 0.47 in Maris and Mordovians, respectively. Regarding the (CTG)11-14 alleles, those containing 13 and 12 trinucleotides were most frequent in all populations; their frequencies varied from 0.15 in Mordovians to 0.24 in Maris and Bashkirs from the Abzelilovskii raion (district). Alleles with large numbers of repeats (more than 30) were only found in Tatars and Bashkirs from the Abzelilovskii raion, where their frequency was 0.01. The data obtained were compared with those on other human populations from various regions of the world. In general, the populations of the Volga-Ural region took an intermediate position between European and Asian populations (although were somewhat more similar to the latter ones) with respect to the distribution of allelic frequencies of the CTG repetitive sequences. In individual populations, the number of genotypes varied from 13 to 27 in Mordovians and Bashkirs from the Ilishevskii raion, respectively. The observed heterozygosity was the highest (91%) in Udmurts and the lowest (58%) in Mordovians; the average heterozygosity was 81%. Such a high heterozygosity, as well as the revealed differentiation of the populations with respect to the distribution of the allelic frequencies of CTG repetitive sequences in the MD gene, allow this polymorphic DNA locus to be considered a highly informative genetic marker of populations.     

北京地区汉族群体D1S1612和D18S535基因座的遗传多态性

采用扩增片段长度多态性（Amp-FLP）分型技术,调查中国北京地区汉族群体D1S1612、D18S535 基因座的遗传多态性,获得等位基因频率分布。结果显示, D1S1612检出9个等位基因,25种基因型, D18S535检出9个等位基因,27种基因型。两个STR基因座的杂和度（H）分别为0.779、0.887;个人识别率（Dp）分别为0.901、0.927;非父排除率（PE）分别为0.564、0.770;多态信息容量（PIC）分别为0.723、0.796,卡方检验表明两个STR 基因座基因型频率分布符合Hardy-Weinberg平衡 (P>0.01 )。D1S1612和D18S535 基因座均属高杂合度、高识别能力的遗传标记,可用于法庭科学亲子鉴定和个人识别。 Abstract: To investigate the genetic polymorphism of D1S1612 and D18S535 in Han population of Beijing. Amp-FLP method was used. 9 alleles, 25 genotypes were observed for D1S1612 locus; and 9 alleles and 27 genotypes for D18S535 locus. All allele frequencies, heterozygosity (H), discrimination power (Dp), exclusion of paternity probability (PE) and polymorphism information content (PIC) were calculated. The allele distributions of the two loci were conformed to Hardy-Weinberg equilibrium (P>0.01). According to the results obtained in this study, it is suggested that both D1S1612 and D18S535 are useful genetic markers for individual identification and paternity testing in forensic science practice as well for genetic study.     

Effective number of breeders and maintenance of genetic diversity in the captive bearded vulture population

We combined pedigree data with data derived from 14 microsatellite loci to investigate genetic diversity and its maintenance in the captive source population for the reintroduction of the bearded vulture into the Alps. We found the captive population to be genetically more variable than the largest natural population in Europe, both in terms of mean number of alleles per locus and mean observed and expected heterozygosity. Allelic diversity of the captive population was higher than, and mean heterozygosity measurements were comparable with the ones found in two large, extinct populations from Sardinia and the Alps represented by museum specimens. The amount of genetic variability recruited with the founders was still present in the captive population of the year 2000, mainly because the carriers of rare alleles were still alive. However, the decline in expected heterozygosity and the loss of alleles over generations in captivity was significant. Point estimates of effective population size, N(e), based on pedigree data and estimates of effective number of breeders, N(b), based on allele frequency changes, ranged from 20 to 30 and were significantly smaller than the census size. The results demonstrate that the amount of genetic variability in the captive bearded vulture population is comparable or even larger than the amount present in natural populations. However, the population is in danger to lose genetic variability over time because of genetic drift. Management strategies should therefore aim at preserving genetic variability by minimising kinship, and at increasing N(e) by recruiting additional founders and enhancing gene flow between the released, the captive and natural populations.     

Population genetics of the vitamin D binding protein (GC) subtypes in the Asian-Pacific area: Description of new alleles at the GC locus

Isoelectric focussing (IEF) in thin layer polyacrylamide gels pH range 4-6.5 has been used to analyse the GC phenotypes of 4233 individuals from 28 different population groups in the Asian, Pacific, and Australian area. Because this technique reveals subtypes of the common GC*1 allele, there is almost a two-fold increase in the mean heterozygosity at the GC locus using IEF compared with conventional electrophoresis. The highest frequency (above 50%) of the GC*1S allele was encountered in Indian populations, reflecting genetic affinities with Europeans. By comparison, east and south east Asians are unique offing maximum values of the GC*1F allele (50%). With the exception of a few Pacific populations which show similar frequencies to east Asians, all other groups in the Pacific area, including Australia, have values of GC*1F similar to GC*1S ranging from 27% to 40%. The GC*2 frequency in most populations varies from 20% to 30%. However, some Polynesian groups have values up to 40% and Australian Aborigines less than 10%. Among other alleles, GC*1A1 is found to be widely distributed among Australian Aborigines and Melanesians and occurs sporadically in Polynesians, Micronesians, and in the Lesser Sunda Islands. Four new alleles, GC*1C24, GC*1C35 Aborigine, GC*1A21, and GC*1A22 are described. The gene frequency data at the GC locus has been used to calculate Nei genetic distances between the populations studied.     

Molecular and genetic characterization of the allelic variants of Du215, Du281, Du323, and Du47G microsatellite loci in parthenogenetic lizard <Emphasis Type="Italic">Darevskia armeniaca</Emphasis> (Lacertidae)

A key issue in the study of unisexual (parthenogenetic) vertebrate species is the determination of their genetic and clonal diversity. In pursuing this aim, various markers of nuclear and mitochondrial genomes can be used. The most effective genetic markers include microsatellite DNA, characterized by high variability. The development and characterization of such markers is a necessary step in the genetic studies of parthenogenetic species. In the present study, using locus-specific PCR, for the first time, an analysis of allelic polymorphism of four microsatellite loci is performed in the populations of parthenogenetic species Darevskia armeniaca. In the studied populations, allelic variants of each locus are identified, and the nucleotide sequences of each allele are determined. It is demonstrated that allele differences are associated with the variation in the structure of microsatellite clusters and single nucleotide substitutions at fixed distances in flanking DNA regions. Structural allele variations form haplotype markers that are specific to each allele and are inherited from their parental bisexual species. It is established which of the parental alleles of each locus were inherited by the parthenogenetic species. The characteristics of the distribution and frequency of the alleles of microsatellite loci in the populations of D. armeniaca determining specific features of each population are obtained. The observed heterozygosity of the populations at the studied loci and the mutation rates in genome regions, as well as Nei’s genetic distances between the studied populations, are determined, and the phylogenetic relationships between them are established.
