    Abstract:
    For the first time, an attempt was made to quantitatively estimate the relative contributions of major racial components to populations of the Volga-Ural region based on the data on allelic polymorphisms of nine loci of the mitochondrial and nuclear genomes. Comparison of the proportions of Caucasoid and Mongoloid characteristics in the gene pools of Bashkirs, Tatars, Chuvashes, Maris, Mordovians, Udmurts, and Komi revealed a heterogeneous pattern. Data on the proportions of major racial components in the nuclear genome indicated that the Caucasoid component was maximum in Mordovians, Komis, and Udmurts. Mongoloid characters were most prevalent in Bashkirs, Maris, Tatars, and Chuvashes. Data on restriction-deletion polymorphism of mitochondrial DNA (mtDNA) also indicated an increased Caucasoid contribution to Mordovian, Udmurt, and Komi gene pools and an increased Mongoloid component in Chuvashes and Tatars. In general, the results obtained agree with ethnic anthropological data indicating the greatest Caucasoid contribution to the Mordovian and Komi gene pools and an increased Mongoloid component in Turkic populations of the Volga-Ural region (Bashkirs, Tatars, and Chuvashes).
