What's the difference between a gamete and a zygote?

生殖细胞和受精卵的区别是什么？

Its stable temperature and high density help preserve and disperse reproductive cells.

稳定的温度和较高的密度有助于保存和分散生殖细胞。

Work is already under way to develop principles for editing reproductive cells.

编辑生殖细胞的定工作已经开始。

" FYI this is probably the first human germ line editing, " Dr. Quake wrote.

“谨供参考：这可能是人类生殖细胞的首次编辑，”奎克写道。

Another, they're releasing reproductive cells called spores.

后来，它们又释放一种叫做孢子的生殖细胞。

This is possible because organisms evolve when random mutations happen in the DNA of reproductive cells.

这是可能的，为当生殖细胞的DNA发生随机突变时，生物就会进化。

Histologically, prominent features include large, round tumor cells resembling germline tumors; or small cells forming Homer-Wright rosettes.

松果体瘤主要的组织学特征包括类似生殖细胞肿瘤中巨大圆形的肿瘤细胞，或是形成Homer-Wright菊形团的小细胞。

Unless land organisms return to the water to reproduce or have specially adapted sex cells, their options are limited.

除非陆地生物回到水中繁殖或有特别适应的生殖细胞，否它们的选择是有限的。

Many algae, for example, have sex cells that are indistinguishable in size.

例如，许多藻类的生殖细胞大小难以区分。

It does not always involve strictly female and male individuals with differently sized sex cells that fuse internally.

它并不总是严格涉及拥有不同大小内部融合的生殖细胞的女性和男性个体。

The other option is the sister chromatids of the x chromosome don't separate in meiosis two in the female germ cell.

女性生殖细胞中，X染色体姐妹染色单体在第二次减数分裂时没有分离。

However, each reproductive cell has only 23 individual chromosomes.

然而，每个生殖细胞只有 23 条独立的染色体。

Germ cells, as they're called, developed inside a fortress-like structure within the testes.

所谓的生殖细胞在睾丸内的堡垒状结构中发育。

And if it's in the germ cells, harmful to generations that come after that.

而且如果是在生殖细胞中，会对后代造成危害。

That's where the so-called germ cells are.

那就是所谓的生殖细胞所在之处。

Okay, and so most of your fertilized offspring gametes are going to perish.

好的，所以你们大部分受精的后代生殖细胞都会死亡。

So you're using germline DNA and assessing that for these risk loci and they're constant.

所以你使用的是生殖细胞DNA，并评估这些风险位点，它们是恒定的。

I, for one, like the idea of for sure Non-germline gene editing.

我倒是挺喜欢肯定不会改变生殖细胞的基编辑这个想法。

So unlike most animals, most plants can produce both male sex cells and female sex cells.

此，与大多数动物不同，多数植物能够同时产生雄性生殖细胞和雌性生殖细胞。

But sex is much more than types of reproductive cells, he and other researchers point out.

但性别远不止是生殖细胞的类型，他和其他研究人员指出。
