[Effect of mutations on the dynamics of numbers of individuals with different genotypes in an isolated heterogeneous population].

The overall (throughout the range) dynamics of the number of diploid individuals possessing n possible gene alleles in a given autosomal locus is studied in an isolated heterogeneous population. The significant influence of new mutations on overall dynamics is shown. It is demonstrated that, under certain conditions, the selection mechanism might have a greater effect on the dynamics of number of individuals with different genotypes in the isolated heterogeneous population than on mutation and "death-reproduction" mechanisms.
