Due to its pivotal geographical location and proximity to transcontinental migratory routes, Iran has played a key role in subsequent migrations, both prehistoric and historic, between Africa, Asia and Europe. To shed light on the genetic structure of the Iranian population as well as on the expansion patterns and population movements which affected this(More)
Although the genetic heritage of aboriginal Siberians is mostly of eastern Asian ancestry, a substantial western Eurasian component is observed in the majority of northern Asian populations. Traces of at least two migrations into southern Siberia, one from eastern Europe and the other from western Asia/the Caucasus have been detected previously in(More)
More than a half of the northern Asian pool of human mitochondrial DNA (mtDNA) is fragmented into a number of subclades of haplogroups C and D, two of the most frequent haplogroups throughout northern, eastern, central Asia and America. While there has been considerable recent progress in studying mitochondrial variation in eastern Asia and America at the(More)
In order to reconstruct the history of Y-chromosome haplogroup (hg) N dispersals in north Eurasia, we have analyzed the diversity of microsatellite (STR) loci within two major hg N clades, N2 and N3, in a total sample of 1,438 males from 17 ethnic groups, mainly of Siberian and Eastern European origin. Based on STR variance analysis we observed that hg N3a(More)
With the aim of uncovering all of the most basal variation in the northern Asian mitochondrial DNA (mtDNA) haplogroups, we have analyzed mtDNA control region and coding region sequence variation in 98 Altaian Kazakhs from southern Siberia and 149 Barghuts from Inner Mongolia, China. Both populations exhibit the prevalence of eastern Eurasian lineages(More)
Phylogenetic analysis of different regions of the mitochondrial genome of the sable showed the presence of several topologies of phylogenetic trees, but the most statistically significant topology is A-BC, which was obtained as a result of the analysis of the mitochondrial genome as a whole, as well as of the individual CO1, ND4, and ND5 genes. Analysis of(More)
Nucleotide sequences of the NADH dehydrogenase subunit 2 gene (ND2) of mitochondrial DNA (mtDNA) were determined in stoats (Mustela ermine) from northeastern Kamchatka. Analysis of the ND2 variability in stoats, which is represented here and, also, in previous studies, shows that the divergence level between American and Eurasian mtDNA haplotypes is about(More)
Based on sequence variation of three nuclear genome genes (BDNF, POMC, and RAG1), the phylogenetic relationships among Asiatic salamanders of the genus Salamandrella, Siberian salamander (S. keyserlingii) and Schrenk salamander (S. schrenkii), were examined. Both species demonstrated high levels of heterozygosity determined by intraspecific polymorphism.(More)
The nucleotide sequence of an extended mitochondrial genome segment (11473 base pairs in size) was determined in the wolverine (Gulo gulo) from Magadan oblast. Phylogenetic and statistical analyses of mitochondrial DNA (mtDNA) sequences of mustelids showed that the separation of the Gulo phylogenetic branch occurred at the Miocene–early Pliocene (about 5.6(More)
To elucidate the effect of natural selection on the evolution of mitochondrial DNA (mtDNA) in Asiatic salamanders of the family Hynobiidae, nucleotide sequences of 12 protein-coding genes were analyzed. Using a mixed effects model of evolution, it was found that, in spite of the pronounced effect of negative selection on the mtDNA evolution in Hynobiidae(More)
