title: [Selection dynamics in a heterogeneous population].
abstract: The dynamics of the number of diploid individuals with possible n > or = 2 alleles of a gene located not in a sex chromosome was studied in heterogeneous isolated population. It was demonstrated that if only selection is accounted for, the number of individuals carrying alleles that do not provide maximal selective advantage approaches zero as the time of observation increases, whereas the number of individuals with various genotypes, but with a maximal selective advantage, approaches non-zero stationary values depending on their initial numbers. It was established that under certain conditions and even if processes of death-multiplication are taken into account, the mechanism of selection may have a dominating effect on population dynamics.
