ABSTRACT

Using the data on five red cell markers (AB0, PGM1, ACP1, GLO1, and ESD) polymorphisms, the population genetic structure of three ethnic territorial groups from the north of European Russia (Continental Nentsy, Kola Saami, and Russian Coast-dwellers) was described. In general, the groups studied a Caucasoid pattern of the frequency distribution of erythrocytic marker alleles. However, a substantial contribution of a Mongoloid component to the Nenets gene pool, expressed as a high frequency of the PGM1*1 allele along with a low frequency of the GLO1*1 allele, was observed. Three ethnic territorial groups examined were close to one another with respect to the distribution of classical biochemical markers. The interpopulation diversity was low (the mean FST = 0.015). The differences observed were for the most part caused by the genetic characteristics of Nentsy. The maximum interpopulation diversity was observed for the GLO1 locus (FST = 0.056).
