In science, we refer to this movement as gene flow.

科学上称之为基因流动。

The genetic diversity was higher within southern populations represented by extensive gene flow.

南方各种群遗传多样性水平较高，且存在广泛的基因流。

Implications of local adaptation and some affecting evolutionary factors, such as selection and gene flow, were also discussed.

在进行生态恢复时也要考虑局部适应，对影响种群局部适应的因素（如选择和基因流）也进行了分析。

That's because of gene flow, which is a fancy way of saying that neighboring species sometimes interbreed.

这是源于基因流动，基因流动意思是相似的物种偶尔会彼此杂交。

Gene flow The movement of alleles within and between populations of the same species through interbreeding.

基因流动:同一种群内由于杂交或种内选择使某一等位基因在该种群内扩散.

The fact that the two populations took independent paths toward developing lighter skin suggests that there was not much gene flow between them.

两种人以各自不同的方式进化出浅色皮肤的事实说明他们之间并没有太多的基因流动。

转基因植物的基因漂移规律及影响因素一直备受关注。

There were gene flow and significant divergence among Chinese yellow cattle breeds.

黄牛不同地方品种之间存在一定程度的基因交流,品种之间出现了显著的遗传分化.

Small population size, non-random mating, mutations and gene flow. However, none of them lead to adaptation.

族群规模小，选择性交配，基因突变和流动。不过这些都不会导致进化适应。
