[Genetic structure of the native populations of the northeastern USSR. I. Distribution of phenotype and gene frequencies in subpopulations of the coast Chukchi].

An analysis of the genotypic structure of three subpopulations of coast chuckchies for 11 polymorphic loci is presented. 1245 individuals were surveyed in total. It is shown that, in spite of variability of phenotypes and gene frequencies in subpopulations, the genotypic structure maintains specific features. In the total sample of coast, a deviation from equilibrium was found for GPT and Gc loci. It is noted that this disequilibrium is maintained for GPT locus in some subpopulations. Such a deviation is probably due to the influence of some systematic factor.
