Study of Eight Blood Protein Polymorphic Systems in Arabian Horses from Turkey

Analysis of the blood protein system was used to study the genetic composition of Arabian horses. Biochemical markers of eight polymorphic loci (Tf, Al, As, AlB, Gc, Hb, PGD, and PGM) were electrophoretically identified in blood samples. A total of 43 phenotypes were identified for these polymorphic systems. The Tf, Hb, and Esloci appeared to be more polymorphic than the other loci studied. Statistically significant differences between the observed and expected genotypic frequencies were found for the PGDandPGMloci (P< 0.05 and P< 0.01, respectively). Individual allele frequencies, observed and expected phenotype frequencies, and the average heterozygosity were estimated for each polymorphic locus.     

Blood group and protein polymorphism gene frequencies for seven breeds of horses in the United States

Gene frequencies at 20 blood group and protein polymorphism loci (A, C, D, K, P, Q, U, Al, Tf, Pi, Xk, Es, Gc, PGD, CA, Cat, PGM, AP, Hb and PHI) are given for seven horse breeds in the United States (Thoroughbred, Arabian, Standardbred, Morgan, Quarter Horse, Paso Fino and Peruvian Paso). These data are used to calculate that the battery of tests is at least 96% effective for recognizing incorrect paternity in these breeds. In addition to paternity testing, these tests can be applied to studies of breed relationships.     

Blood group and protein polymorphism gene frequencies for seven breeds of horses in the United States

Gene frequencies at 20 blood group and protein polymorphism loci ( A, C, D, K, P, Q, U, Al, Tf, Pi, Xk, Es, Gc, PGD, CA, Cat, PGM, AP, Hb and PHI ) are given for seven horse breeds in the United States (Thoroughbred, Arabian, Standard bred, Morgan, Quarter Horse, Paso Fino and Peruvian Paso). These data are used to calculate that the battery of tests is at least 96% effective for recognizing incorrect paternity in these breeds. In addition to paternity testing, these tests can be applied to studies of breed relationships.     

Polymorphic biochemical systems in a population of newly arrived inhabitants of the northeastern USSR. IV. The characteristics of the genetic structure of persons with chronic pathological processes

Analysis of properties of the genetic structure in 2847 individuals with different chronic diseases (1261 men and 1586 women) for 14 polymorphic loci (AcP, PGM1, PGD, GPT, GLO-I, EsD, AK, Pp, E2, Hp, Gc, Tf, AB0 and Rh) is presented. Discrepancy between the observed and expected phenotype frequencies for PGM1, GLO-I, EsD and AB0 loci is observed in a sample of patients Deviation from the expected frequencies is unequal for the representatives of different sex. Male and female portions of the sample differ significantly from each other for AcP, GPT, GLO-I, AK, EsD, Tf and AB0 loci, i. e. for 7 from 14 systems analysed. Highly significant differences between healthy and sick individuals have been detected: in general samples for 8 loci (AcP, PGM1, GPT, GLO-I, AK, Pp, Hp, AB0); in men for 8 loci (AcP, GPT, AK, PGD, Pp, Tf, AB0); in women for 5 loci (PGD, Pp, Gc, Tf, AB0). The difference between sick and healthy individuals of different sex is not only of qualitative but also of quantitative expression. The difference between sick and healthy men is much stronger, as compared to that between women. A decline in the average heterozygosity is noted in sick individuals. From the results obtained it is possible to conclude that the group of different pathologic conditions for the complex of genetic parameters differs significantly from that of healthy individuals. This may be a reflection of adaptation and disadaptation processes under the extreme environmental conditions.     

Genetic studies of blood markers in Przewalski's horses

Ninety-six Przewalski's horses (Equus przewalskii) were blood typed using systems of inherited blood variants known to be highly effective for parentage testing of domestic horses (E. caballus). Sixteen red cell antigenic factors detected using sera prepared by alloimmunization of domestic horses were shown to be inherited in six systems (A, C, D, P, Q, and U) and in the same patterns as domestic horses. Family data confirmed autosomal, codominant inheritance at five loci of serum protein variants (Al, Tf, Xk, Pi, and Es) and three loci of red cell proteins (PGM, PHI, and Hb). One serum protein locus (Gc) and two red cell protein loci (PGD and CA) appeared to be monomorphic. Despite the narrow genetic base and high inbreeding coefficients of captive Przewalski's horses, average heterozygosity calculated over 18 loci was estimated to be 0.320 +/- 0.05, which was similar to that found in five breeds of domestic horses.     

Genetic structure of the populations of native inhabitants in the northeastern USSR. V. The Chukot Evens

The genetic structure of two Chukot Evens subpopulations (314 individuals) for electrophoretic protein systems and taste sensitivity to PTC was studied. 17 of the 39 loci were polymorphic (43.59%). The following systems were completely monomorphic: diaphorase NAD H (Dia); glucose-6-phosphate dehydrogenase (G-6-PD); glutamatoxalate transaminase (GOT); carbonic anhydrase (Ca-1); catalase (Ct), lactate dehydrogenase (loci LDH-A and LDH-B); leucine aminopeptidase (Lap); malate dehydrogenase (MDH); purine nucleoside phosphorylase (PNP); superoxide phosphorylase (PNP); superoxide dismutase (SOD); phosphoglucomutase-2 (PGM2); cholinesterase (locus E1); red cell esterase (4 loci); albumin (Alb); hemoglobin (Hb A and B); ceruloplasmin (Cp); and blood, gren, using the standard method. The following systems were polymorphic: red cell acid phosphatase (AcP); phosphoglucomutase-1 (PGM1); 6-phosphogluconate dehydrogenase (PGD); glutamatepyruvate transaminase (GPT); glyoxalase-1 (GLO-1); esterase (EsD); adenilatkinase (AK); alkaline phosphatase (Pp); cholinesterase (locus E2); haptoglobin (Hp); transferrin (Tf); group-specific component (Gc) and ABO, MN, Lewis, P blood groups and taste sensitivity to PTC. The following allele frequencies for polymorphic loci have been detected: AKI = 0.994; GLO = 1I = 0.082; GPT1 = 0.653; AcPA = 0.400; AcPB = 0.599; AcPC = 0.001; PGDA = 0.944; PGM1(1) = 0.906; EsD1 = 0.897; E2+ = 0.048; HpI = 0.394; GcI = 0,919; Tfc = 0.987; r(O) = 0.669; p(A) = 0.184; q(B) = 0.146; M = 0.711; Le = 0.411; P1+ = 0.521; t = 0.295. The genetic structure of Chukot Evens population is significantly nearer to that of the other ethnic groups of the North-East, in comparison with the genetic structure of Evenks of the Middle Siberia.

Variability of polymorphic gene markers in Buryat and Russian newborns from Ulan-Ude]

Variability of ten polymorphic loci (ABO, RhD, PGD, ACP, PGM1, GLO, ESD, ADA, GC, TF) was studied in 326 Buryat and 310 Russian newborns from Ulan-Ude city. Marked differences between two groups were observed in the distributions of allelic frequencies of ABO, RhD, PGD, ACP, PGM1, GLO, ESD, GC loci. Genetic similarities between Buryat and other mongoloids were estimated. Close similarity was observed between Buryat, Mongols, Yakut and Kyzyl.     

Genetic structure of the populations of native inhabitants of the northeastern USSR. IV. The Koryaks of Kamchatka

Genetic structure of four Kamchatka subpopulations (675 individuals) was estimated for 25 erytrocyte and serum systems, some blood groups and for taste sensitivity to PTC. 23 of 38 loci examined are completely monomorphic. These are: AK, Ca-1, Cat, Dia, Est1-4, GOT, G-6-PD, LDH A and B, MDH, PGM2, SoD, Hb alpha and beta, ChE1, Lap, Alb, Cp, Tf, Rh. Following allele frequencies were found for polymorphic loci: AcPA = = 0.616; AcPB = 0.383; AcPC = 0.0015; EsD1 = 0.882; GLO - I1 = 0.156; GPT1 = 0.611; PGDA = = 0.959; PGM1(1) = 0.953; ChE2+ = 0.039; Gc1 = 0.888; Hp1 = 0.173; r(0) = 0.620; P(A) = 0.201; q(B) = 0.179; le = 0.192; M = 0.397; P1+ = 0.585; t = 0.371. According to monomorphic and polymorphic loci set, Kamchatka Koryaks are rather similar to other ethnic North-East Asiatic groups, being the most approximate to Reindeer Chuckchies and the most remote from Alaskan and Asiatic Eskimos. In other words, the extent of genetic differences between Kamchatka Koryaks and North-East populations corresponds to the geographic distribution and the degree of ecological differences in these populations. Analysis of interpopulation heterogeneity permitted to reveal the extent of contribution of individual loci to "differentiation" of North-East ethnic groups. The possible influence of ecological factors on interpopulation and intersubpopulation heterogeneity of the loci analysed is discussed.     

Genetic blood markers in Arabian, Barb and Arab-Barb horses in Morocco

Gene frequencies at 16 blood group and protein polymorphism loci (A, C, D, K, P, Q, U, Al, Gc, Es, A1B, Tf, PGD, PGM, GPI and Pi) are given for three horse breeds in Morocco (Arabian, Arab-Barb and Barb). These data are used to calculate average heterozygosity (h), Nei's standard genetic distance (D_N) and probability of exclusion (PE). Variability expressed as the average heterozygosity was lower in the Arabian (0.330 ± 0.066), while it was higher and almost the same in the Arab-Barb (0.413 ± 0.071) and the Barb (0.414 A ± 0–070). The shortest genetic distance was found between Barb and Arab-Barb. The 16 loci used are at least 95% effective for recognizing incorrect paternity in these breeds. The Barb and Arab-Barb genetic profiles obtained showed the rare variants interesting perhaps in the context of European and American breeds: notably D^cfgkm, D^dekl, Es-N, Tf-A and Pi-W.     

Blood genetic markers in the Chinese of two eastern provinces

A total of 205 Han Chinese from two eastern provinces (155 from Fujien and 50 from Hopeh) were tested for the distribution of six blood groups--A1A2BO, MN, Rhesus (CcDEe), Lewisa, Kell (Kk) and Fya--four serum proteins--albumin and haptoglobin types; transferrin and group-specific component subtypes--haemoglobin, and twelve red cell enzyme systems--glucose-6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, lactate and malate dehydrogenases; acid phosphatase, esterate-D, glyoxalase I, adenylate kinase, glucose-phosphate isomerase, phosphoglucomutase (locus 2), and superoxide dismutase types; and phosphoglucomutase (locus 1) subtypes. The frequencies of blood groups were more or less within the reported frequencies in the Chinese. However the frequency of le was much lower in the present series. The Chinese are characterized by low p1, Ro, k, le, and a high Fya in general. P2 was lacking in the Chinese. There were some differences in the blood group frequencies in the two provinces. The frequencies of Hp alleles; Tf and Gc subtypes show characteristic mongoloid features with high Hp1, TfD, and GcIF. The frequency of TFC2 was higher in the Fujien province than that in Hopeh. At the hemoglobin locus only one Hb AD was detected, while the frequency of the beta-thalassemia trait was 0.03. No red cell G6PD deficiency or variant was detected. The distribution of red cell enzymes showed Mongoloid characteristics with low PGDC, AK2, ESD1, GLO1, and higher pa. PGM1 subtypes also had Mongoloid characteristics with lower PGM2+ and higher PGM2-. The phenotypic distribution of all the fifteen polymorphic loci was at Hardy-Weinberg equilibrium in both the Chinese populations.     

Materials for studying the gene pools of Russia and neighboring countries: the Russian population of the Pskov region

The distributions of the genes and haplotypes for blood groups ABO, MN, Rhesus, P1, Lewis, and Kell-Cell-ano and biochemical markers of the genes of loci HP, GC, C'3, Tf, 6PGD, GLO1, ESD, ACP1, and PGM1 (including subtypes) were studied in 116 Russian subjects born in the Pskov oblast. Differences of this group from other Russian populations with respect to genetic structure were found.     

Probable assignment of the serum cholinesterase (E1) and transferrin (Tf) loci to chromosome 1 in man.

Suggestions of linkage in males between the E1 and Rh loci (Z = + 1.849; THETA = 0.20) and between the Tf and Rh loci (Z = + 0.595; THETA = 0.35) are presented. The assignment of the E1 and Tf loci to chromosome 1 and the order Tf:E1:PGD:Rh:PGM1 are cautiously proposed.     

Genetic structure of the Mongols as derived from the ABO, MN, Rh, EsD, GLO1, PGM1, AcP, 6-PGD, Hp, Gc, Tf, C'3 and ChE2 loci

According to integral characterization of gene frequencies of the investigated loci AB0, MN, Rh, GLO1, PGM1, EsD, AcP, 6-PGD, Hp, Tf, Gc, C'3 and ChE2, Mongolian population has high level of polymorphism, with the exception of haplotypes R" (cdE) and Ry(CdE) at the Rh locus and TfB0-1 at the Tf locus. The data on biochemical and immunological polymorphic gene markers analysed in the population of Mongolia show that the Mongolians have some distinctive features, in comparison with the mean-in-the-world characteristics: high frequencies of the B genes at the AB0 locus; D, E, R1 and R2 at the Rh locus; GLO11, PGDc, TfDChi, E2(C5+), PGM1(1+); low frequencies of the genes A(AB0), R0(Rh), AcPc, Hp1, Gc2, C'3F, PGM 1(2-); the rest of the genes at the above-mentioned loci and the genes of the locus MN have the mean-in-the-world frequencies.

Transferrin and haemoglobin polymorphism in domesticated goats in the USA

The distribution of transferrin (Tf) and haemoglobin (Hb) polymorphisms in five goat breeds in the USA is reported. Two Tf types, A and B, were identified. A significant difference in frequency (P less than 0.05) was observed only between the Spanish and Alpine goats. Haemoglobin beta-globin variants, Hb beta A, Hb beta D and Hb beta E were observed with isoelectric focusing at pH ranges 5-8 and 6.7-7.7. Hb beta D was not found in the Alpine and Angora breeds. Haemoglobin allelic frequencies varied widely and differed significantly (P less than 0.05) among breeds.     

Species relationship in the Pennisetum gene pool: enzyme polymorphism

Summary Variation in leaf esterases (EST), 6-phosphogluconate dehydrogenase (PGD), shikimate dehydrogenase (SKDH), leucine aminopeptidase (AMP), phosphoglucomutase (PGM) and malate dehydrogenase (MDH) is reported in the Pennisetum gene pool. In the primary gene pool, polymorphism for EST, AMP, SKDH was very high, as compared to the near-monomorphic isozymes of PGD. Two loci controlling leaf esterases Est-1 and Est-2, were identified in the primary gene pool. Differences in allelic frequency distribution of the polymorphic Est-1 locus occur between the cultivated and wild pearl millet. The prevalent alleles of Est-1 are absent in P. purpureum Schumach (secondary gene pool). A monomorphic band of the -esterase-specific Est-2 locus was identified in most of the secondary gene pool accessions, P. squamulatum Fresen and an accession of P. pedicellatum. SKDH and EST revealed differences between most of the tertiary gene pool species. By contrast, a PGD zymogram was prevalent in several species of different sectional taxa. Gene duplication for PGD isozymes occurs in the diploid species, P. ramosum, of the tertiary gene pool. Heterodimers of PGD and EST were observed in the hybrid between pearl millet and P. squamulatum, whereas a monomeric structure characterized SKDH and AMP.     

Protein polymorphism in native goats from central Argentina

Under the name of Creole goats, individuals of various origins, morphological and productivity characters are grouped. To characterize the genetic pool of goats from different sources in central Argentina, protein polymorphism revealed by electrophoresis was analyzed. A total of 109 adult animals from Santa Marı́a, Colón and Ischilı́n Districts, Córdoba Province, were studied. The red cells lysates were subjected to starch gel electrophoresis and specific staining procedures to reveal the activity of different enzymes and hemoglobin. Separation of plasmatic proteins was carried out by electrophoresis in polyacrylamide gel and stained with Coomassie Blue. From a total of 14 loci analyzed, eight were polymorphic in at least one flock. Four codominant alleles were detected in the locus βHemoglobin (βHb); three alleles in malic enzyme (Me), glucose 6 phosphate dehydrogenase (G6pdh) and lactate dehydrogenase (Ldh) and two alleles in catalase (Cat), transferrin (Tf), esterase-2 (Es-2) and phosphoglucomutase (Pgm). In all the cases, the observed genotype frequencies were not significantly different from those expected from Hardy–Weinberg equilibrium. The proportion of polymorphic loci (P%) varied between 21.4% and 42.9% and mean heterozygosity (H), between 0.061 and 0.117. Alleles at loci Cat, Me and Es-2 showed significantly different frequencies according to the sample origin. The flock from Colón District presented the highest levels of polymorphism. This is the only stock which includes hybrids of varying grade between Creole stocks and male specimens from Saanen and Nubian breeds.     

Genetic markers in the blood of three species of tamarins (Saguinus mystax, S. labiatus and S. oedipus)

Alkaline phosphatase (Alp), esterase-I (Es-I), esterase-II (Es-II), carbonic anhydrase (CA), cell esterase (cEs), esterase-D (Es-D), isocitrate dehydrogenase (ICD), malate dehydrogenase (MDH), 6-phosphogluconate dehydrogenase (PGD), tetrazolium oxidase (To), ceruloplasmin (Cp), Haptoglobin (Hp) and hemoglobin (Hb) in 58-75 samples of three species of tamarins (Saguinus mystax, S. labiatus and S. oedipus) were detected by means of horizontal starch gel electrophoresis. Two types (Es-I 1 and Es-I 2) for Es-I, four types (Es-II 1, Es-II 2, Es-II 3 and Es-II 2-3) for Es-II, three types (cEs 1, cEs 2 and cEs 1-2) for cEs, three types (PGD 1, PGD 2 and PGD 1-2) for PGD, two types (To 1 and To 2) for To, and three types (Hp 3, Hp 1-3 and Hp 2-3) for Hp were observed. However, Alp, CA, Es-D, ICD, MDH, Cp and Hb were monomorphic. In the S. mystax, no Es-II or PGD variants were observed. No Es-II variant was seen in the S. oedipus. Gene frequencies of cEs, PGD and Hb were biased in the three species. It is concluded that six polymorphic loci are useful as genetic markers for a species or individual.
