Polymorphism of Y-Chromosomal Diallelic Loci in Populations of the Volga–Ural Region

Polymorphism of Y-Chromosomal Diallelic Loci in Populations of the Volga–Ural Region Three diallelic polymorphisms of human Y chromosome (DYS287(Y Alupolymorphism, YAP), T/C transition at the RBF5locus (Tat), and G/A transition at the LLY22locus) were studied in eight ethnic populations of the Volga–Ural region, representing Turkic branch of the Altai (Bashkirs, Tatars, and Chuvashes) and Finno-Ugric branch of the Uralic linguistic family (Maris, Mordovians, Udmurts, Komi-Zyryans, and Komi-Permyaks), and in the group of Slavic migrants, belonging to the Indo-European linguistic family (Russians). The Volga–Ural populations were characterized by a low frequency of the Y chromosome Aluinsertion. Examination of an association between the Alupolymorphism and Tatmutation revealed absolute YAP–/C linkage. Analysis of the haplotype frequency distribution patterns constructed from the data on the DYS287and RBF5polymorphisms revealed substantial differences between Udmurts and other populations. The differences were also observed between Komi-Zyryans and the populations of Bashkirs, Mordovians, Komi-Permyaks, and Russians. Analysis of the degree of genetic differentiation pointed to high level of genetic differentiation of the male lineages of the Finno–Ugric ethnic groups. The data on the linkage between the RBF5locus and the LLY22locus mutations indicated the common origin of the Tatmutationin Bashkirs, Mordovians, Udmurts, and Komi-Zyryans, and of a number of ancestralCallele-bearing Y chromosomes in Tatars, Maris, and Chuvashes. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals
