The genetic composition of the Russian population was investigated by analyzing both mitochondrial DNA (mtDNA) and Y-chromosome loci polymorphisms that allow for the different components of a population gene pool to be studied, depending on the mode of DNA marker inheritance. mtDNA sequence variation was examined by using hypervariable segment I (HVSI)(More)
We investigated the frequency of different repeat-length alleles of the trinucleotide CAG microsatellite repeat in the coding sequence of the nuclear gene for the catalytic subunit of mitochondrial DNA polymerase gamma (POLG) in 12 ethnic groups from northern Eurasia. The population sample consisted of 1,330 individuals from 3 large geographic areas:(More)
The first data on mtDNA diversity in Besermyan, the Finno-Ugric ethnic group, related to Udmurts, are presented. An analysis of mtDNA polymorphism showed that Besermyan stood out from the other populations of Volga-Ural region due to the presence of a large proportion of the mongoloid component. The sample of Besermyan contained East Eurasian haplotypes not(More)
