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

然后是配子减数裂，因为它们（配子）是不同的。

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

第一次裂，即第一次减数裂后，配对的同源染色体离。

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

第二次裂，也就是第二次减数裂后，每个染色体的姐妹染色单体离。

There are two types of cell division: Mitosis and Meiosis.

裂有两种类型：有丝裂和减数裂。

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

减数裂 2 的最终结果是产生 4 个单倍体，n 条染色体；(人类为 23 条)。

Meiosis 2 Meiosis 2 is the second meiotic division and usually involves equational segregation, or separation of sister chromatids.

减数裂 2减数裂 2 是减数裂的第二次裂，通常涉及相等的离，或姐妹染色单体的离。

Telophase 1 The first meiotic division effectively ends when the chromosomes arrive at the poles.

末期 1当染色体到达两极时，第一次减数裂有效地结束。

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

但是在出生的时候，卵母停止发育——它们卡在减数裂的第一阶段。

The answer lies within the amazing process of meiosis.

答案就在惊人的减数裂过程中。

This tells the secondary oocyte to get ready to complete its second meiotic division.

这告诉次级卵母准备完成第二次减数裂。

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

减数裂 2 的四个主要步骤是：前期 2、中期 2、后期 2 和末期 2。

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

在减数裂过程中，一个裂两次，形成四个子。

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裂 II，它们产生的子总共有四个圆形精子。

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

这些初级精母随后进入减数裂一期，形成两个较小的单倍体，称为次级精母。

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

这基本上是指在减数裂第二阶段会裂，特别是指软骨鱼。

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

这些减数裂的变化也可能导致疾病。

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

现在我们可以直接进入减数裂和克雷布循环。

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

简而言之，在减数裂过程中， 即产生配子 [3] 的过程中，会发生染色体交叉。

First one is crossing over during meiosis.

第一个是减数裂期间的染色体交叉互换。

Similar to mitosis, cells also pass through the Interphase, G1, S and G2 phase before they enter Meiosis.

与有丝裂相似，在进入减数裂之前也经历了间期、G1、S 和 G2 期。
