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

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，我们发现这片覆盖 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，此不同的珊瑚可以拥有相同的基。)潜水员珊瑚礁和近海复育场四散开来，对每个基个体收集两个碎片。

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

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

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，为它们可以有性繁殖，但实际上它们也会自然分裂，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.

有丝分裂发生生长、细胞修复和无性繁殖，会复制出一模一样的细胞，这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，可能根本不会发生这种情况。

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.

这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，这是中第一例雌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.

通过这个视频，你现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.

这对山杨来说是非常危险的情况，为山杨非常依赖整体无性繁殖的持续增长。
