[Genetic and ecological study of aboriginal inhabitants of the Siberian northeast. IV. Genotype and genetic structure of three modern populations of Yakutia].

Three separate and reproductively isolated populations living at present in boreal forest and tundra area in Eastern Siberia were studied. Blood groups (AB0, MNSs, Rhesus, Duffy, P. Diego), immunoglobulin allotypes--G1m (z, a, x, f), G3m (b, b0, b1, b3, s, t), Hp, Tf, PGM1, AcP, 6-PGD were tested in blood samples obtained from total 570 individuals.

[Genetic and ecologic study of aboriginal inhabitants of the Siberian northeast. III. Demographic structure of three modern population links of Yakutia].

Demographic data of genetic interest were studied in three separate populations of Tungus-speaking Evens. They are characterized as expanding populations, rather as a result of migration and admixture, than due to natural increase. The mean and variance of livebirths per female, whose reproduction was completed, were 7.

[Gametic disequilibrium in populations of reindeer Chukchi and Asian Eskimos].

Ten local populations of Reindeer Chukchi and four local populations of Asiatic Eskimos were surveyed for variation of nine polymorphic loci (MN, Ss, Cc, Ee, Duffy, AcP, PGM1, Hp, G3M). Pairwise linkage disequilibria were estimated from multilocus genotype frequencies using the Hill's method. Large amounts of linkage disequilibrium were found for the two pairs of linked genes MNSs and CcEe.

[Genetic and ecological study of aboriginal populations of northeastern Siberia. I. Gm-haplotypes and their frequency in 10 chukchi populations. Genetic structure of reindeer chukchi].

G1m (z, a, x, f) and G3m (g, b0, b1, b3, b5, s, t) allotypes were tested in 1079 Chukchi inhabitants of interior Chukotka and adjacent Kamchatka. Genetic variation at this particular locus is provided by the presence of three haplotypes, namely, za;g, zax;g and za;bO35st, revealed with mean frequencies of 0.748, 0.

[Genetic and ecological study of aboriginal populations of northeastern Siberia. II. Polymorphic blood systems, immunoglobulin allotypes and other genetic markers in asian eskimos. Genetic structure of Bering sea eskimos].

Blood groups, immunoglobulin allotypes, serum proteins and red cell enzymes were tested in four populations of Asiatic Eskimos. 12 of 16 gene loci studied were found to be polymorphic. Analysis of covariance and variance matrices for gene frequencies of 8 Bering Sea populations revealed major aspects of regional genetic structure.
