Mitochondrial DNA diversity in Siberian Tatars of the Tobol-Irtysh basin
- First Online:
Data on the variation of the nucleotide sequence of hypervariable segment I (HVSI) and restriction fragment length polymorphism (RFLP) of the coding region of mitochondrial DNA (mtDNA) have been used to characterize the mitochondrial gene pool of Siberian Tatars of the Tobol-Irtysh basin (N = 218), one of three geographic/linguistic groups of Siberian Tatars. The gene pool of Siberian Tatars has been shown to contain both Asian and European mtDNA lineages at a ratio of 1.0 : 1.5. The mtDNA diversity of Siberian Tatars is substantially higher than that of other Turkic-speaking populations of North and Central Asia. The position of the mitochondrial gene pool of Tatars of the Tobol-Irtysh basin in the genetic space of northern Eurasia populations has been determined.
