Their allele frequencies at numerous genetic loci 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。
Instead, each allele of the gene sets out a series of probabilities.
此基因的等位基因有这一系列的可能性。
The risk gene divides the world into two camps -those who have the FTO allele and those who don't.
