inviable

In postzygotic isolating mechanisms mating occur, but the resulting hybrid organism is inviable or sterile.

在合子后隔离机制中，匹配可以进行，产生杂种杂种育。

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个体比以两个方向进行杂交个体繁殖后代要多，了产生无生机杂种，就要消耗掉一些配子。
