ETHNOGENETICS OF KOMI-ZYRYANS ACCORDING T O DISTRIBUTION OF GENE-FREQUENCIES OF ERYTHROCYTE AND SERUM SYSTEMS OF BLOOD-GROUPS

Distribution of gene markers of blood groups (ABO, RH, MN, KEL, and FY ), erythrocyte enzymes (SOD-A and 6-PGD) and serum proteins (Hp, Gc, T f, and ChE(2)) was studied in 10 ethnographic and geographic groups of Komis. Some of the groups studied differ significantly in the allele frequencies-B-ABO (0.163-0.289), Fy(a) (0.496-0.693), K (0.018-0.076)- and in haplotype frequencies of RH system-CDe (0.237-0.403), cDE (0.21 9-0.351), and cde (0.225-0.425). Average gene frequencies in Komis are considered in regard to ethnogenesis of the nation. It is demonstrate d that Komis are genetically close to Finno-Ugrian ethnic groups of th e Ural territory, but are different from Baltic Finns.
