The Tatars of Eurasia: peculiarity of Crimean, Volga and Siberian Tatar gene pools

We have studied the gene pools of populations with «Tatar» enthonym in three regions of Eurasia - Tatars of Crimea, Tatars of Volga region and Tatars of Siberia. About 1000 individuals of these peoples were analyzed on 50 SNP markers of Y-chromosome, the most informative tool in population genetics. Ethnoterritorial groups of Tatars were found to be genetically different, we didn’t found their common ancestry component. The Westasian and Mediterranean genetic components (population of Asia Minor and Balkans) predominate in the gene pool of Crimea Tatars, the Eurasian steppe component is much fewer. The genetic variants of Ural and North Europe predominate in the gene pool of Volga Tatars, the genetic components of Asia Minor and Central Asia are much fewer. The populations of Siberia Tatars are very variable. Some includes the prominent Siberian genetic component, other has predominated genetic lineages from southwest regions of Eurasia. Consequently the gene pools of all the Tatar ethnoterritorial groups were formed based on the indigenous population with genetic flow of migrations from other regions.
