Instead, it reverts to its asexual state and then grows up again.

它会从性成熟回复到幼虫无性阶段然后重新变性成熟。

Hamilton even tackled the thorny question of why sex exists when asexual creatures can reproduce so much faster than those that mate.

First, some organisms reproduce asexually, so they don't need other organisms to produce offspring.

首先，有些生是无性繁殖的，所以它们不需要其他生来繁殖后代。

But, thanks to genetic testing, we've learned that this stand of aspen covering 106 acres of land is actually a single clonal organism that grew from a lone seed long ago.

不过，正是由于基因检测，我们片覆盖 106 英亩的山杨实际上是由很长时间前的一粒种子无性繁殖出来的。

(Coral can reproduce asexually, making clones of themselves, so separate corals can have the same genes.) Divers fanned out across the reef and offshore nurseries, collecting two fragments of each genetic individual.

(珊瑚可以无性繁殖，将自己克隆，因此不同的珊瑚可以拥有相同的基因。)潜水员在珊瑚礁和近海复育场四散开来，对每个基因个体收集两个碎片。

By cloning themselves with 'virgin births' and reproducing sexually, aphids maximise their chances of survival.

通过" 单性生殖" 的无性繁殖以及有性繁殖，蚜虫使它们的生存机会最大化。

Almost all jellyfish species have evolved to reproduce both sexually and asexually, allowing them to increase their numbers with or without a partner.

几乎所有种类的水母都进化成有性繁殖和无性繁殖，使得它们在有无伴侣的情况下都能繁殖。

Corals are really special because they reproduce sexually, but also they actually naturally fragment and so they are asexually able to also reproduce.

珊瑚非常特别，因为它们可以有性繁殖，但实际上它们也会自然分裂，因此它们也能够无性繁殖。

Mitosis produces identical copies of cells and is involved in growth, cell repair, and asexual reproduction, which is how simple organisms reproduce.

有丝分裂生在生长、细胞修复和无性繁殖，会复制出一模一样的细胞，是简单生体繁殖的方式。

Often lust comes first, but not always. For some people who are asexual, it may not happen at all.

通常情欲是第一位的，但并非总是如此。对于一些无性恋者来说，可能根本不会生种情况。

A couple of years later, Pando grew mature enough to reproduce asexually.

几年后，潘多生长成熟，足以进行无性繁殖。

This cycling between sexual and asexual phases is called the alternation of generations, and it helps keep plants flourishing, from Granddaddy Succulent to Great-grandbaby Succulent — and even beyond that.

种有性和无性之间的循环被称为世代交替，它有助于保持植的繁盛，从祖孙多肉植到曾孙多肉植，甚至更远。

The researchers said they believe it is the first case of asexual reproduction in any bird species where the female had access to a mate.

研究人员表示，他们认为，是鸟类中第一例雌鸟在有交配机会的情况下进行的无性繁殖。

From this video, you should now know that mitosis is how cells divide in order to grow and repair, or for asexual reproduction.

通过个视频，你在应该知道有丝分裂是细胞为了生长和修复或无性生殖而分裂的过程。

And that's a really dangerous situation for aspen because it really depends on continuous growth of the whole clone.

对山杨来说是非常危险的情况，因为山杨非常依赖整体无性繁殖的持续增长。
