[Gametic disequilibrium in populations of reindeer Chukchi and Asian Eskimos].

Ten local populations of Reindeer Chukchi and four local populations of Asiatic Eskimos were surveyed for variation of nine polymorphic loci (MN, Ss, Cc, Ee, Duffy, AcP, PGM1, Hp, G3M). Pairwise linkage disequilibria were estimated from multilocus genotype frequencies using the Hill's method. Large amounts of linkage disequilibrium were found for the two pairs of linked genes MNSs and CcEe. The same pattern of non-random association between unlinked loci PGM1 and AcP was found in all subpopulations of both tribes that is induced by natural selection.
