繁殖后代

Insects propagate themselves by means of eggs.

昆虫以卵繁殖后代。

Individuals crossing exclusively within the same population produce more progeny than those crossing in both directions and thereby use up some of their gametes for the production of inviable hybrids.

完全在同一种群内进行杂交比以两方向进行杂交繁殖后代多，因此为无机杂种，就消耗掉一些配子。
