    Abstract:
    This article continues the series of publications on the population genetic structure of the Tuva Republic. The polymorphism of immunological (ABO, MN, and the Dd locus of Rhesus) and biochemical (TF, GC, HP, PGD, PGM1, ACP1, and ESD) marker systems was studied in three rural populations of the Tuva Republic: the Shinaanskii, Todzhinskii, and Bai-Taiginskii populations (the Kungurtug, Toora-Khem, and Teeli villages, respectively). Genetic subdivision of the populations and genetic distances between the Tuvinian populations and the populations of neighboring regions were estimated. Tuvinians were demonstrated to be genetically heterogeneous. Data on their population-genetic structure with respect to several classical marker systems agree with the results obtained for quasigenetic (family names) and molecular (mtDNA) markers. Prolonged isolation of individual populations in the republic promoted formation of specific patterns of gene frequencies in some of them. These patterns account for differences between Tuvinians and other populations belonging to the Altaic language family. Tuvinians in general are genetically closer to Mongolian populations inhabiting the regions bordering the Tuva Republic than to southern Altaians.
