[Genetic structure of 2 isolated populations of native inhabitants of Sibiria (Northern Altaics) according to the results of a study of blood groups and isoenzymes].

The article comprises the results of the investigation of the frequencies of alleles of 9 gene loci controlling the blood groups, isoenzymes in populations and subpopulations of Cumandinians and Chelkanians. The presence of alleles A2 r(cde) and K at low concentrations was discovered in both groups. The method of genetic distances was used for the investigation of the inter- and intragroup divergence. With respect to certain loci a considerable variation of allelic frequencies from village to village was established.
