Y chromosomes in Volga-Ural region

Genetika. 2001 Jul;37(7):1002-7

Analysis of Y-chromosomal diallelic loci polymorphism in populations of the Volga-Ural region

Bermisheva MA et al.

Three diallelic polymorphisms of human Y chromosome, DYS287 (Y Alu polymorphism, YAP), T/C transition at the RBF5 locus (Tat), and G/A transition at the LLY22 locus, were studied in eight ethnic populations of the Volga-Ural region, representing Turkic (Bashkirs, Tatars, and Chuvashes) and Finno-Ugric (Maris, Mordovians, Udmurts, Komi-Zyryans, and Komi-Permyaks) branches of the Uralic linguistic family, and in the group of Slavic migrants, belonging to the Indo-European linguistic family (Russians). Ethnic populations of the Volga-Ural region were characterized by a low frequency of the Y chromosome Alu insertion. Examination of an association between the Alu polymorphism and Tat mutation revealed absolute C/YAP linkage. Analysis of the haplotype frequency distribution patterns constructed from the data on the DYS287 and RBF5 polymorphisms revealed substantial differences between Udmurts and the other ethnic 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 mutations of the RBF5 and the LLY22 loci indicated the common origin of the Tat mutation in Bashkirs, Mordovians, Udmurts, and Komi-Zyryans, and of a number of ancestral C allele-bearing chromosomes in Tatars, Maris, and Chuvashes.

Nobody seems to remember Herodotus's allegation that the Gelonoi, southern neighbours on the Volga of the Boudinoi who were pretty definitely the ancestors of the Komi (& now linguistically of the Udmurt or Votyak also) were Greek colonists of unknown date, who had partly adopted the language of the Boudinoi. When I read Bjorn Collinder's description of the Udmurt/Votyak as much darker & more aquiline than the Komi (which he attributed to Iranian or Turkic admixture), I immediately wondered whether they are not rather descendants of the "Greek" Gelonoi, though now having adopted the language & the name (UD-murt or VOT-yak) of the Boudinoi. I was also struck by their institution of the "kenos", a common (koinos) or perhaps empty (kenos) barn, filled with harvested produce to be shared by the whole community.
