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，匹配可以行，但或不产生杂或杂不育。

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.

完全在群内行杂交个体比以两个行杂交个体繁殖后代要多，因此为了产生无生机杂，就要消耗掉些配子。
