Abstract

Some specific peculiarities of gene markers distribution among northern Selkups were examined. High frequencies of the AB0*0 allele (0.7091) and the RH*cDE haplotype (0.3457) are typical for Selkups. The values of these markers draw Selkups together with few Siberian ethnic groups and Amerindians. Haptoglobin allele frequencies in studied groups were similar to their distribution among European populations. Rare alleles of TF, PI and ACP1 genes were not observed, possibly due to a small number of studied groups. Distribution of GC factors reflects ethnic and geographic specificity. A decrease of the ESD*2 allele frequency is observed from south to north, from East Asia to the Taymyr Peninsula. High frequency of PGM1*1+ allelo-morph (0.7101) in Selkups apparently correlates with the cruelty of climatic conditions of North Asia. An increasing PGM1*2+ proportion apparently is connected with prolonged circumpolar migrations reflecting ancient interrelations between Samodian and Finno-Ugrian peoples. The high LCT*D allele frequency in Selkups is similar to the frequency of lactase deficiency among mongoloid populations in general. Several unusual polymorphisms previously reported in Amer-indians were present in northern Selkups. Selkups are characterized by a number of genetic fea-tures bringing them together with natives of the New World, which is an evidence of distinctly manifested signs of the residual ancient Upper Palaeolithic layer.
