outbreeding

The benefit of outbreeding might be explanation enough for the vigour of their offspring.

我们只要观察一下那些精力十足的幼畜就能知道远系繁殖的好处。

At the same time, however, the propensity to choose someone with slightly similar genes can also avoid the problem of outbreeding- the mixing of genes that are too different.

然而，与此同时，选择稍微相似基因的人为配偶也能避免远系繁殖差异太大的基因组合问题。

Selfing heterozygotes halves the heterozygosity, and thus outbreeding maintains heterozygosity and produces a more adaptable population.

自交杂合子有一半杂合性，因此远系繁殖可以产生适应能量更强的种群。
