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

然后是配子减数分裂，因为它们（配子）是不同的。

During the first cellular division called meiosis I, the chromosomal pairs are separated.

第一次细胞分裂，即第一次减数分裂后，配对的同源体分离。

The answer lies within the amazing process of meiosis.

答案就在惊人的减数分裂过程中。

In the second cellular division called meiosis II, the sister chromatids of a given chromosome are separated.

第二次细胞分裂，也就是第二次减数分裂后，每体的姐妹单体分离。

The end result of meiosis 2 is production of four haploid cells, n chromosomes; (23 in humans) .

减数分裂 2 的最终结果是产 4 单倍体细胞，n 体；(人类为 23 )。

But right around birth, the oocytes stop developing — they get stuck in the first stage of meiosis.

但是在出的时候，卵母细胞停止发育——它们卡在减数分裂的第一阶段。

The four main steps of meiosis 2 are: prophase 2, metaphase 2, anaphase 2, and telophase 2.

减数分裂 2 的四主要步骤是：前期 2、中期 2、后期 2 和末期 2。

During meiosis, one cell divides twice to form four daughter cells.

在减数分裂过程中，一细胞分裂两次，形成四子细胞。

They then rush through meiosis II, and their resulting daughter cells total four round spermatids.

然后它们快速通过减数分裂 II，它们产的子细胞总共有四圆形精子细胞。

These primary spermatocytes then go into meiosis I, and form two smaller haploid cells called secondary spermatocytes.

这些初级精母细胞随后进入减数分裂一期，形成两较小的单倍体细胞，称为次级精母细胞。

These structures are critical for the process of cell division in next step at meiosis 1.

这些结构对减数分裂 1 的下一步细胞分裂过程至关重要。

It's basically where cells will split in the second stage of meiosis, and specifically elasmobrachs.

这基本上是指细胞在减数分裂第二阶段会分裂，特别是指软骨鱼。

It can also, these changes in meiosis can lead to disorders.

这些减数分裂的变化也可能导致疾病。

Here are the distinct phases of meiosis: INTERPHASE MEIOSIS 1 CYTOKINESIS 1 MEIOSIS 2 CYTOKINESIS 2.

减数分裂的不同阶段是：间期，减数分裂 1，胞质分裂 1，减数分裂 2，胞质分裂 2。

Now we can go straight onto meiosis and the Kreb cycle.

现在我们可以直接进入减数分裂和克雷布循环。

To put it simply, during meiosis, the process in which gametes[3] are created, chromosomal crossover occurs.

简而言之，在减数分裂过程中， 即产配子 [3] 的过程中，会发体交叉。

First one is crossing over during meiosis.

第一是减数分裂期间的体交叉互换。

Mitosis is used to make all the cells in our body, meiosis just makes gametes, or sex cells.

有丝分裂用于制造我们身体里的所有细胞，而减数分裂只是制造配子，也就是性细胞。

The secondary oocyte stops in metaphase of meiosis 2, and waits for fertilization as the menstrual cycle transitions into the luteal phase.

次级卵泡会在第二次减数分裂中期停止分裂，并且在卵泡期向黄体期转换的时候等待受精。

To do this, the primary oocytes have to complete meiosis 1, and in a person's lifetime only about 400 successfully do that.

要变成配子就必须要经历第一次减数分裂，而一人的一中大概只有400初级卵母细胞可以做到。
