1·Gene flow is relatively free because individuals can move and then mate with individuals in their new location.

基因流动是相对自由的，因为个体可以移动，然后在新的地方与个体交配。

2·In the absence of gene flow between the subpopulations, genetic differences between the groups begin to accumulate.

在亚群体间缺乏基因流动时，群体间的遗传差异开始累积。

3·The change separated populations of insects now living along opposite shore, completely cutting off gene flow between them.

这个变化使当地的昆虫被分隔开来，现在分居于河的两岸，彼此的基因流动已被完全截断。

4·So, even under normal situations, the gene flow among the subpopulations is more of an intermittent trickle than a steady stream.

所以即使在正常条件下，这些亚物种间的基因流动也更像是一条断断续续的细流，而不是一条不停流淌的小溪。

5·Gene flow, the movement of alleles across the range of the species, is relatively free because individuals can move and then mate with individuals in their new location.

基因流动，即等位基因在整个物种范围内的移动，是相对自由的，因为个体可以移动，然后在新的地点与个体交配。

6·If two flying insect populations took up residence in separate nearby valleys, chances are that individuals from each population would fly back and forth, continuing gene flow.

如果有两个飞行昆虫种群居住在相距不远的不同山谷中，那么任一种群中的个体都有可能来回飞行，从而使基因流动继续。

7·Such a dramatic increase in straying from damaged areas to more pristine streams results in substantial gene flow, which can in turn lower the overall fitness of subsequent generations.

从受损区到更原始流区的基因流的数量急剧增加，导致了大量的基因流动，进而降低了后代的总体适应性。

8·Scientists have stopped asking if such gene flow is possible.

科学家已经不再怀疑这样的基因流通是否可能发生。

9·The experiment is mostly restricted to the potential gene flow.

这项试验多半只涉及可能的基因流动。

10·Gene flow is an important factor influencing the genetic structure of plant populations.

基因流是影响植物种群的遗传组成和遗传结构的重要因子。
