[Koryak of Kamchatka. The genetic differentiation of the population].

It has been established that by the set of loci the average standardized genetic variance, Fo, is within an anticipated interval of changeability = 0.0602 less than Fo less than fil = 0.0978 and does not significantly differ from the estimates of fe. The present value of differentiation of the population, Fo, corresponds to the selectively neutral equilibrium between the random drift of genes and migrations. The changeability of loci MNSs, Rhesus, Duffy has a selectively neutral character, whereas that of loci P, Lewis, Kell has an adaptive character. The genetic structure of the koryak population is, on the whole, under a great stabilizing pressure. The genetic differentiation is expressed as a time equivalent, T = 5818 years.
