Genetic and ecological study of aboriginal inhabitants of northeastern siberia russian sfsr ussr ii. polymorphic blood systems immunoglobulin allotypes and other genetic markers in asiatic eskimo genetic structure of eskimo from the bering sea area



Genetika 22(9): 2369-2380



Blood groups, immunoglobulin allotypes, serum proteins and red cell enzymes were tested in four populations of Asiatic Eskimos. 12 of 16 gene loci studied were found to be polymorphic. Analysis of covariance and variance matrices for gene frequencies of 8 Bering Sea populations revealed major aspects of regional genetic structure. Regression of average heterozygosity on genetic distance from centroid permitted us to interprete it in the light of counterbalancing action of systemic and non-systematic pressure. Analysis of R matrix containing gene frequencies for both Eskimo and Chukchi populations revealed two different clusters.sbd.more heterogeneous Eskimo cluster and less heterogeneous Chukchi cluster. Good fit was observed between regional genetic structure history and geography.
