Genetic relationships between 14 native Spanish breeds of goat

Summary. The genetic distances separating 14 Spanish goat breeds are calculated from gene frequency data of 14 genetic blood markers (GSH, Ke, Hb, Dia, Ct, MDH, CA, X, NP, Alp, Am, Cp, Tf and Al).
Working from the matrix of Nei's genetic distances we drew a dendrogram demonstrating a great genetic similarity among populations from Negra Serrana, Zamorana, Guadarrama, Retinta, Blanca Andaluza, Berciana and Pirenaica on one hand; and Canaria, Murciana, Blanca Celtibérica, Verata, Palmera, Malaguena and Granadina on the other.
We discuss the similarities and differences within our classification using gene frequency data of the blood genetic markers studied, and classifications based chiefly on morphological and production data.

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.     

Genetic polymorphism in Spanish Merino sheep

A Spanish Merino sheep population is characterized, for the first time, according to its frequencies for a total of nine polymorphic loci: three blood group factor systems, A, B and C, and the following red cell or serum polymorphisms: haemoglobin (Hb), carbonic anhydrase (CA), 'X protein', transferrin (Tf), arylesterase (EsA) and albumin (Al). Another locus, amylase (Am), did not show polymorphism.     

A study on the Changthangi pashmina and the Bakerwali goat breeds in Kashmir: I. Analysis of blood protein polymorphisms and genetic variability within and between the populations

Blood samples of 483 Pashmina goats and 392 Bakerwali goats were taken from the Ladakh and Jammu provinces, respectively, for characterisation of the breeds by polymorphic enzymes and proteins. Furthermore, the sex, age, body weight and hematocrit of both breeds and the pashmina yield of Pashmina goats were recorded. Polymorphisms of 12 enzymes and proteins (albumin (Al), alkaline phosphatase (Alp), amylase (Amy), NADH-diaphorase 1 (Dia1), vitamin-D-binding protein (Gc), haemoglobin (Hb), hemopexin (Hpx), nucleoside phosphorylase (Np), malic enzyme (ME), phosphohexose-isomerase (PHI), transferrin (Tf), X-protein (X)) in blood plasma and hemolysate were determined using gel electrophoresis. Out of 12 protein systems, 10 were found to be polymorphic. In four systems (Al, Amy, Dia1, Hpx) new phenotypes were detected. To estimate the genetic variability within breeds, the degrees of heterozygosity, deviations from the Hardy–Weinberg-equilibrium (HWE) and F_IS-, F_ST-, and F_IT-values were estimated. In comparison with literature data both breeds show slightly higher variability than other goat breeds, with degrees of heterozygosity ranging from 15 to 25% and 24 to 26% in the Pashmina and Bakerwali goat populations, respectively, and the percentage of polymorphic loci ranging from 50 to 67%. On the other hand, a decrease of variability at some loci can be observed in both breeds. Deviations from HWE in combination with a deficiency of heterozygote genotypes were observed in all sub-populations apart from the Pashmina sub-population ‘Likir’. Genetic differences between the goat breeds could be quantified through calculation of Nei’s genetic distances ranging from 0.002 to 0.080. With exception of the Pashmina sub-population ‘Likir’, lower distance values were found between sub-populations within the respective breeds.     

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.     

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.     

Eight polymorphic blood protein systems in Arab 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, Es, 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 Es loci appeared to be more polymorphic than the other loci studied. Statistically significant differences between the observed and expected genotypic frequencies were found for the PGD and PGM loci (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.

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 groups and serum protein polymorphisms in the Pitman-Moore and Ohmini strains of miniature pigs

The variations of blood groups and biochemical polymorphisms in the populations of the two miniature pig strains reared in Japan were investigated in this report. The variations in eight blood group systems were investigated by using serological techniques, and five serum protein systems by using starch gel electrophoresis. The Pitman-Moore strain showed no variations in K, O, Tf, Cp and Am systems, but showed plymorphisms in A, E, F, G, H, L, Pa and Hpx systems. The Ohmini strain showed no or little variations in E, F, G, Tf, Pa and Cp systems, but showed polymorphisms in A, H, K, L, O, Hpx and Am systems. From the results of investigation of genetic similarities among nine pig populations including various breeds, it was made clear that the two miniature pig strains were very different genetically, and the Pitman-Moore strain was genetically closer to European large pig breeds than to East Asian native pigs, while the Ohmini strain was close to Thai and Philippine natives.     

An investigation of five genetic loci controlling polymorphic variants in the red cells of goats*

Results of a joint study carried out in South Africa and England to search for new genetic markers in the blood of goats are presented. Haemoglobin (Hb) phenotypes were reinvestigated with the technique of isoelectric focusing; frequencies in different goat breeds are given. Anaemic Hb type A, AB and B goats all produced a Hb C with an identical electrophoretic pattern. All goats tested had identical carbonic anhydrase (CA) types, but showed polymorphism of ‘X’ protein. Preliminary results indicated that nucleoside phosphorylase (NP) may be polymorphic.     

利用12个血液蛋白和非蛋白标记分析同羊起源及系统地位

采用典型群随机抽样在陕西省白水县抽取同羊样本。采用淀粉凝胶和醋酸纤维薄膜检测12个的结构基因座位的遗传多型性,结果在同羊中发现10个多型座位：运铁蛋白（Tf）、碱性磷酸酶（Alp）、亮氨酸氨肽酶（Lap）、芳基酯酶（Ary-Es）、血红蛋白β（Hb-β）、X-蛋白（X-p）、碳酸酐酶（CA）、过氧化氢酶（Cat）、苹果酸脱氢酶（MDH）和赖氨酸（Ly）;而白蛋白（Al）和后白蛋白（Po）为单态。采用遗传贴近度和系统关系聚类分析两种方法分析同羊起源及系统地位。结果表明两种方法均支持同羊属于蒙古羊系统,同羊起源于蒙古羊,这与同羊的育成史实相符。和聚类分析方法相比,遗传贴近度分析方法可以更为有效地用于中亚以东南绵羊群体的血统判别,可以更有效地反映同羊的育成过程。     

Genetic polymorphism analysis among nine endogamous population groups of Maharashtra,India

The present paper reports results of analysis of 14 genetic marker systems-ABO, MN, Rh, Hp, Tf, Cp, Alb, AcPH, PGM, LDH, MDH, Est-D, Hb and G-6-PD studied on a number of subjects of 9 endogamous groups of Maharashtra: Bhils, Katkaris and Pawaras, (all tribal groups); Deshastha Rigvedi and Chitpavan (two Brahmin groups); Nava Budhas (a scheduled caste); Chandrasenya Kayastha Prabhu and Marathas (two middle caste groups); and Parsis a migrant group from west Asia. Analysis of heterogeneity of gene frequencies reveal considerable heterogeneity for most of the loci among these groups.     

Population genetic study in ten endogamous groups of West Bengal, India

Ten endogamous population groups of West Bengal (India)--Rabhas, Garos, Mechs, Rajbanshis, Jalia Kaibartas, Bagdis, Lodhas, Mundas, Brahmins, Vaidyas--have been typed for twelve polymorphic systems: ABO, Gm, Km, Hp, Cp, Tf, Alb, Hb, aP, EsD, AK and PGM1. The results are compared with those obtained on other Indian populations. Serological and anthropometric data, which have been included into population comparisons, reveal a considerable genetic variability of the groups under study. This variability is obviously connected with the population history of West Bengal.
