英语语法分析

If inbreeding is bad, then the opposite - outbreeding - should be good.

如果同系繁殖不好，那么与之相反的远系繁殖就应该好。

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。

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。
