Com parative analysis of the data on mtDNA variation in the populations of Eastern Europe showed that Volga Tatars were characterized by low interpopulation differentiation (FST = 0.33%), while the level of interethnic differentiation in Eastern Europe is 1.8%. Genetic similarity of Tatars from the eastern regions of Tatarstan to Bashkirs, as well as of Tatars from western regions to Chuvashes, with whom they share territorial borders, was revealed. Positive correlation between population genetic structure in Eastern Europe and linguistic affil iation of the ethnic groups studied was observed.
