| Summary: | Abstract-Autosomal gene pools of 27 populations representing 12 ethnic groups of Siberia, Central Asia, and the Far East have been characterized for the first time using a set of eight polymorphic Alu insertions. The results of our analysis indicate a significant level of genetic diversity in populations of northern Eurasian and the considerable differentiation of their gene pool. It was shown that the frequency of the Alu (-) allele at the CD4 locus was inversely related to the magnitude of the Mongoloid component of the gene pool: the lowest and highest frequencies of the CD4 Alu deletion were recorded in Eskimos (0.012) and in Russians and Ukrainians (0.35), respectively. A gene flow analysis showed that Caucasoid populations (Russians, Tajiks, and Uzbeks), as well as Turkic ethnic groups of southern Siberia (Altaians and Tuvans), Khanty, and Mansi populations, in contrast to ethnic groups of eastern Siberia and the Far East, have been recipients of a con siderable gene flow. A correlation analysis showed that genetic distances determined using polymorphic Alu insertions were correlated with the anthropological characteristics of the populations studied. |
