Genetic Interrelation of the Chulym Turks with Khakass and Kets according to Autosomal SNP Data and Y-Chromosome Haplogroups

The structure of the gene pool of the Chulym Turks, Kets, Khakass and other South Siberian populations was studied using microarrays and Y-chromosome markers. The results of the analysis of the frequencies of autosomal SNPs by various methods, the similarity in the composition of the Y-chromosome haplogroups and YSTR haplotypes indicate that the gene pool of the Chulyms was formed during the resettlement of Turkic groups from the territory of Khakassia and their mixing with the local autochthonous population. Two dominant Y-chromosome haplogroups in the Chulyms and haplotype clusters demonstrate the founder effect, the formation age of which is fully consistent with the data on their ethnogenesis. Analysis of the composition of the genetic components and IBD blocks demonstrates their genetic affinity with the Kets, Khakass, and Tomsk Tatars. This confirms the information about the formation of their gene pool as a result of the mixing of alien and indigenous populations of the Chulym basin.
