[Koryaks of Kamchatka. The genetic characteristics and formation of a gene pool].

Investigation of korak population of Kamchatka is carried out for 10 non-linked blood groups loci, serum proteins, PTC taste and ABH antigens secretion. The korak population enters in the system of Middle Asian mongoloids for the genetical characteristics studied. Koraks occupy an intermediate position between Siberian and Far East populations in their genetic pecularities, revealing the most close genetical similarity with Siberian population. The main contribution in the genofond of ancient korak athnic community is carried by neolytic inhabitants of Siberia.
