Immunoglobulin Allotypes in Several North American Eskimo Populations

Abstract

Genetic data consisting of immunoglobulin testing (GM and KM) from 631 Eskimos from 5 populations are reported. These populations are Savoonga, Gambell (St. Lawrence Island), Wales, King Island, and Mckenzie Delta, Baffin Island. The GM and KM haplotypes are analyzed and compared to those occurring in Greenland, Canadian, Alaskan, and Siberian Eskimos and to other Siberian indigenous populations. These analyses suggest that during the peopling of the New World, four separate migrant groups crossed Beringia at various times.
