Abstract

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.

摘要

在一个隔离的异质群体中,研究了在给定常染色体位点上拥有n种可能基因等位基因的二倍体个体数量的整体(在整个范围内)动态变化。研究表明新突变对整体动态变化有显著影响。结果证明,在某些条件下,选择机制对隔离异质群体中不同基因型个体数量动态变化的影响可能比对突变和“死亡-繁殖”机制的影响更大。
