Abstract:

Mitochondrial DNA (mtDNA) restriction polymorphism was examined in Turkmens, Eastern Iranians, and Ukrainians. The gene pools of all populations studied were characterized by the presence of European mtDNA lineages. Mongoloid component observed in Turkmen and Iranian populations with the frequencies of about 20% was represented by groups C, D, and E/G in Turkmens, and by M*, D, A, and B in Iranians. The relative positions of the populations studied, of populations from the Caucasus, Western Iran, and Russian populations from the Krasnodar krai and Belgorod oblast in the space of principal components revealed a geographically specific pattern of the population clustering. The data on mtDNA polymorphism indicated pronounced differentiation of Eastern and Western Iranians. The latter were characterized by a mtDNA group composition similar to that in Eastern Slavs. The historical role of the Caspian populations in the formation of the population of Southeastern Europe is discussed.
