Abstract
We for the first time have examined the autosomal gene pool of the Siberia, Central Asian and the Far East populations (27 populations of 12 ethnic groups) using a set of polymorphic Alu insertions in the human genome. The results of the analysis testify (i) to a significant level of genetic diversity in the Northern Eurasian populations and (ii) to a considerable differentiation of gene pool in the population of this region. It has been shown that at the CD4 locus, the frequency of Alu (-) is inversely related to the Mongoloid component of the population, the lowest and highest frequencies of the Alu deletion at locus CD4 were recorded respectively in Eskimo (0.012) and Russian and Ukrainian (0.35). The analysis of gene flow proved Caucasoid populations (Russian, Tajik and Uzbek), as well as those of Turkic ethnic groups from the Southern Siberia (Altaians and Tuvinians) and Khanty and Mansy populations to be the recipients of a considerable gene flow from the outside of the concerned population system, as compared with the East Siberian and the Far East ethnic groups. The results of the correlation analysis received with use polymorphic Alu insertion testify to the greatest correlation of genetic distances with anthropological characteristics of populations.
