Their allele frequencies at numerous geneticloci gradually become more and more different as new alleles independently arise by mutation in each population.
随着新等位基因在每个群体中独立突变产生，它们在许多遗传位点上的等位基因频率逐渐变得越来越不同。

Three new geneticloci have been identified with involvement in subtle and quantitative variation of human eye colour.
三种新的基因位点与人眼颜色的微小及定量变化有关。

Stereotypies as quantitative trait that are affected by both multiple geneticloci and non-genetic factors may be controlled by the possible presence of one or more major genes.
