杂交

Note that artificial selection involves crossbreeding between genetic varieties of the same species and thus is not a form of speciation.

请注意，人工选择涉及杂交品种间的遗传相同的物种，因而不是一种形态。

As I see it, all media have their own characteristics and advantages, but this crude 'crossbreeding' seems a little bland.

在我看来，传媒都有着各自的特色与优势，生硬地"杂交"显得不伦不类。

For species, adaptations to novel environments and the need to avoid crossbreeding with those on the other side of the split are both plausible hypotheses.

对于物种，适应新环境的需要和避免与分化的另一方杂交都是貌似有理的假设。
