The change separated populations of insects now living along opposite shore, completely cutting off gene flow between them.
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。
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.
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。
So, even under normal situations, the gene flow among the subpopulations is more of an intermittent trickle than a steady stream.
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。
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.
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。
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.
这项试验多半只涉及可能的基因流动。
The experiment is mostly restricted to the potential gene flow.
科学家指出，作物和其野生亲属之间的基因流动相似，难以控制。
The researchers point out that gene flow between crops and their wild relatives is common and difficult to contain.
能干扰这种自然平衡的外界因素有选择、突变、基因流动以及自然选择。
Forces that can disturb this natural Balance are selection, mutation, gene flow, and natural selection.

通过再造林将这两个区域中的任意一处与冈贝连起来，公园里的黑猩猩就会因为基因流动和种群规模的扩大而受益，但它们也可能会因为其他族群的疾病扩散而受到打击。
If either area could be linked to Gombe by reforested corridors, the chimps would benefit from increased gene flow and population size. Then again, they might be hurt by sharing diseases.
