The Eskimos and Chuckchi of the Chuckotka Peninsula were studied at 13 loci of serum and erythrocyte proteins and enzymes by electrophoresis. Six loci—including albumin, transferrin, carbonic anhydrase I and II, monoamine oxidase, and superoxide dismutase—were monomorphic in the studied populations. The mean frequencies of alleles in nine polymorphic loci of Chuckotka Eskimos and Chuckchi, Eskimos of Alaska, Canada, and Greenland, some Mongoloid populations of Siberia, American Indians, and Lapps of circumpolar areas of Western Europe were obtained. The genetic distances between these populations were calculated. The Eskimos of Chuckotka were closest to the Alaskan Eskimos. The relative heterozygosity of Chuckotka Eskimos was calculated and was the highest in Chuckchi. The average heterozygosity in Eskimo populations increased in the following order, from least to greatest: Chuckotka Eskimos, St. Lawrence Island Eskimos, Alaskan Eskimos, Greenland Eskimos, and Canadian Eskimos. The average heterozygosity of the Chuckchi was similar to that of Western Hemisphere Eskimos.
