title: [Analysis of distribution of "mongoloid" haplogroups of mitochondrial DNA among indigenous population of the Tuva Republic].
abstract: Variation of Mongoloid-specific restriction sites of mitochondrial genome was analyzed in three territorial groups of Tuvinians. Distribution of mitochondrial DNA haplogroups A, B, C, and D on the territory of the Tuva Republic was estimated. The populations studied did not display distinct differentiation in respect to the mtDNA polymorphism. The specific feature of Tuvinian mitochondrial gene pool was the prevalence of only one haplogroup C (over 40%), mainly represented by two mitotypes. The high frequency of this haplogroup makes Tuvinians similar to more northern Siberian populations. On the other hand, the presence of haplogroup B indicates that Tuvinians have affinity to ethnic groups of Central Asia.
