[Polymorphism of immunogenetic and biochemical markers in Siberian (Tobol-Irtysh) Tatars].

The polymorphism of immunogenetic and biochemical markers has been studied in nine populations of five ethnic-geographic groups of Siberian (Tobol-Irtysh) Tatars. Data on the frequency distributions of 33 alleles and 6 haplotypes of 14 loci (ABO, RHD, RHC, RHE, P, KEL, HP, C'3, TF, GLO1, ESD, ACP, PGD, and PGM1) in sample of 354 subjects have been obtained. Comparison with other ethnic groups has shown that the gene pool of Tobol-Irtysh Tatars contains an ancient autochthonic genetic stratum similar to that found in the neighboring Ob' Ugrian population. Genetic relationships of various strengths with Central Asian Turks and the ethnic groups of the Volga region have been found, which apparently reflect different stages of the ethnogenesis of the Tobol-Irtysh Tatars.
