[Biochemical polymorphism in the northern fur seal, Callorhinus usinus, from 3 regions of the northwestern part of the Pacific Ocean].
Polymorphism for the number of the blood proteins (transferrin, alkaline phosphatase, haptoglobin, plasma esterase and erythrocyte esterase) have been exposed by means of starch gel electrophoresis of northern fur seal Callorhinus ursinus from three regions: Pelagic of Commander Islands (n = 164), Rockery of Robben Island (Sakhalin population, n = 308), winter todder region to the east of Honshu Island (n = 110). The reliable differences have been exposed between fur seals of the Commander and Sakhalin populations by the gene frequencies Tf and Es pl. Fur seals from winter todder region turned out to be closer to Commander population, that to the Robben one. However, originality of gene frequencies of locus Ap (alkaline phosphatase), revealed from the todder region animals, is difficult to explain by the mixture of the Commander and Robben population only. Perhaps, this originality is caused by the influence of Pribylov population. It is established that hemoglobin of northern fur seal consists of two components (Hb I + Hb II). Individual variability of hemoglobin results in the variation of the colour intensity of the "slow" component (Hb II).
