[Normal and adverse genetic processes in subdivided populations of the island type: computer simulation].

A computer model simulating genetic dynamics of a subdivided population at the level of a one-locus diallele system is proposed. In contrast to the earlier publications, this model is based on Wright's island model. The computer experiments were focused on genetic changes occurring during relatively short time intervals comparable to the duration of economic activities of humans (tens of generations). The process of attaining stationary state and reorganization of the genetic structure of the system under anthropogenic influence were simulated. The results are interpreted graphically as a spatial-temporal distribution of subpopulations by classes of gene frequencies as well as in quantitative terms of Nei's G-statistics.
