But at this point, the mutation causing 90% male offspring would no longer be an advantage.

但基于这一点，这种能产生 90% 的雄性后代的变异不再是一种优势。

Specifically he had produced no male offspring to serve as heir, as he had been Julius Caesar's heir.

尤其是他没有男性后代来做继承人，就像他是尤利乌斯·凯撒的继承人。

Son Son is a male child, a male offspring.

Son Son是男的孩子，是男性的后代。

Australian brushtail possum moms, for example, invest more resources in their daughters, so when these resources are scarce, they have more male offspring.

例如澳大利亚毛尾负鼠妈妈们在她们女儿身上付出了更多的资源，因此当她们资源有限的时候，她们就会有更多的雄性后代。

So male offspring are a bigger risk in general — at all stages, they're more likely to die, and even if they live they might not reproduce.

所以一般来说，雄性后代的风险比较大——在各个阶段，他们死亡的可能性比较大，即使活下来也可能无法繁殖。

But because mitochondrial DNA is inherited from an animal's mother, these domestic genes can be ferreted out by breeding the male offspring of clones with captive females.

但是因为线粒体 DNA 是从动物的母亲那里遗传下来的，所以可以通过将克隆的雄性后代与圈养的雌性交配来找出这些家养基因。

They are the Israelites who are to be given wholly to me. I have taken them as my own in place of the firstborn, the first male offspring from every Israelite woman.

因为他们是从以色列人中全然给我的，我拣选他们归我，是代替以色列人中一切头生的。

It altered the genes of some male mosquitoes so that when they mate with females only their male offspring would survive, meaning the number of females should crash within a few generations.

它改变了一些雄性蚊子的基因，因此当它们与雌性交配时，只有雄性后代能够存活下来，这意味着雌性蚊子的数量应该会在几代人之内急剧下降。
