Then there is Meiosis for our gametes, because they (gametes) are different.

然后是减数分裂，因为它们（）是不同。

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

生殖细胞和受精卵区别是什么？

Remember that gametes only have 23 chromosomes rather than the normal 23 pairs.

记住，只有 23 对染色体，而不是正常 23 对。

Either way the separation doesn't happen and the end result is a gamete with an extra X chromosome.

不管是哪种情况，都发生了不分离现象，最后结果都是产生了多一条X染色体。

Klinefelter syndrome develops when a gamete, either sperm or egg, contains at least one extra X chromosome.

异常在时期就存在了，精和卵都有可能发生，异常会多出至少一条X染色体。

And this results in one gamete with a pair of x chromosomes one without any and potentially two normal gametes.

这导致产生一个有两条X染色体：一个没有X染色体，以及两个有可能正常。

The primary oocyte has 46 chromosomes, but eventually it has to turn into a gamete with only 23 chromosomes.

初级卵母细胞有46条染色体，但是最终会变成只有23条染色体。

The gametes take half of the genes and shuffle them.

会拿取并打散一半基因。

" We've been able to preserve certain types of cells since the 1950s, in particular gametes, red blood cells, cancer cells."

“自20世纪50年代以来，我们就已经能够保存某些类型细胞，特别是、红细胞和癌细胞。”

So if a parent plant made spores, its offspring would make gametes, then its offspring would make spores, and so on.

因此，如果亲本植物产生孢，它后代就会产生，然后它后代就会产生孢，以此类推。

Richardson discusses only transgenerational epigenetics, the kind that can be passed down to a gamete or embryo.

理查森只讨论了跨代表观遗传学， 即可以传递给或胚胎那种。

Do I need to mention the fact that a male's gamete producing organs sit dangerously exposed outside the body?

我是否需要提及雄性产生器官危险地暴露在体外这一事实？

The first time, they do this separately when they generate the gametes - that is, sperm and egg cells.

一次是在牠们各自在造时重组─即是制造精和卵时。

Typically a gamete with 23 chromosomes, including one sex chromosome either X or Y, develops when parent germ cells undergo the process of meiosis.

正常包含23条染色体，其中有一条X或Y性染色体，由亲代生殖细胞减数分裂产生。

The cycle alternates between two different types of generations: one with only half its DNA — called the gametophyte generation because it makes gametes, or eggs and sperm.

这种循环在两种不同类型世代之间交替进行：一种世代只有一半 DNA，它被称为体世代，因为它产生，或卵和精。

Klinefelter Syndrome is a genetic abnormality in which at least one additional x chromosome is inherited by an XY male as a result of impaired meiosis in the parental gametes.

Klinefelter综合征是一种基因异常病；本该以XY为基因型男性多得到一条X染色体，从而患病，这通常是亲代减数分裂异常结果。

In Klinefelter syndrome, the sex chromosome pairs which is either XX or XY don't separate in meiosis I in the male or female germ cell and this resulted in two gametes with a pair of X chromosomes and two gametes without X chromosomes.

Klinefelter综合征中，对XX或XY性染色体对在父亲或母亲一次减数分裂中没有分离，从而产生了两个有两条X染色体以及两个没有X染色体。

If failure also happens during meiosis in these germ cells as they give rise to gametes, other XXXXY, XXXY and XXYY genotypes that also lead to Klinefelter syndrome can result including the rare situation where there's an additional Y chromosome.

如果有丝分裂和减数分裂均发生了不分离，那么这类Klinefelter综合征患者基因型就可能是XXXXY，XXXY和XXYY等，包括了同时多出一条Y染色体罕见情况。
