生殖隔离

A principal challenge in testing the role of natural selection in speciation is to connect the build-up of reproductive isolation between populations to divergence of ecologically important traits.

检验自然选择在物种形成中的作用的一个主要挑战是，将生殖隔离的出现与有着生态学重要性的特征联系起来。

The Ecuadorian population examined by Kronforst and his colleagues shows the same white and yellow variation found in Costa Rica but has not yet reached a level of strong reproductive isolation.

通过科瑞·福特斯和他的同事的调查得出，厄瓜多尔的蝴蝶种群与哥斯达黎加的蝴蝶种群一样，都具有白色与黄色种群的变异，但是并未达到一种显著的生殖隔离的水平。

they may , however , be at least partially isolated from each other reproductively and occupy different ecological niches.

它们和其他个体至少存在部分的生殖隔离因而占有不同的生态位。

Transgenic technology can break the species isolation and utilize the gene of other species.

转基因技术可以打破物种间生殖隔离，转化利用其他物种有益基因。

Inherited reproductive isolation is the basic criterion of species.

透过遗传上的生殖隔离是种的基本标准。
