A STUDY OF THE GENE POOL OF YASKOLBINSK TOBOL-IRTYSH SIBERIAN TATARS ACCORDING TO STR-MARKERS OF THE Y-CHROMOSOME

Abstract

The paper discusses the results of a study of the gene pool of Yaskolbinsk Tobol -Irtysh Siberian Tatars of Tyumen region according to STR-markers of the Y-chromosome. The sample is formed of 86 men living in Achirsk and Laytamaksk rural settlements in Tobolsk region. The main research method was the analysis of highly variable microsatellite STR-markers of Y-chromosomes using the Y-filer set on the Applied Biosystems 3130 xl Genetic Analyzer sequencer. Genotyping of DNA samples in the gene pool of Yaskolbinsk Tatars found eight Y-chromosome haplo-groups (J2b-M12, N1b-P43, L2-M317, N1c-LLY22, N-M231, O3-M122, R1a-M198, R1b1-M73) with the major haplogroup of N1b-P43.Relatively low diversity of Y-chromosome haplogroups in the population of Yaskolbinsk Tatars may be due to the effect of genetic drift, due to their small size and geographical isolation. It was also noted that the gene pool of Yaskolbinsk Tatars shows similarities with the gene pool of a number of other Turkic peoples of Siberia, in particular, with such peoples of the Altai-Sayan region, as the Shors and the Altaians.
