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

减数分 2减数分 2 是减数分的第二次分，涉及相等的分离，或姐妹单的分离。

The answer lies within the amazing process of meiosis.

答案就在惊人的减数分过程中。

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

然后是配子减数分，因它们（配子）是不同的。

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

细胞分有两种类型：有丝分和减数分。

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

第一次细胞分，即第一次减数分后，配对的同源分离。

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

在减数分过程中，一个细胞分两次，形成四个子细胞。

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，卵母细胞停止发育——它们卡在减数分的第一阶段。

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

减数分 2 的最终结果是产生 4 个单倍细胞，n 条；(人类 23 条)。

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

减数分的不同阶段是：间期，减数分 1，胞质分 1，减数分 2，胞质分 2。

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

这告诉次级卵母细胞准备完成第二次减数分。

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

然后它们快速过减数分 II，它们产生的子细胞总共有四个圆形精子细胞。

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

第二次细胞分，也就是第二次减数分后，每个的姐妹单分离。

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一期，形成两个较小的单倍细胞，称次级精母细胞。

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

末期 1当到达两极时，第一次减数分有效地结束。

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

现在我们可以直接进入减数分和克雷布循环。

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

与有丝分相似，细胞在进入减数分之前也经历了间期、G1、S 和 G2 期。

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

简而言之，在减数分过程中， 即产生配子 [3] 的过程中，会发生交叉。

Meiosis 1 takes place in following steps: Prophase 1 Prophase 1 is typically the longest phase of meiosis.

减数分 1 按以下步骤进行：前期 1前期 1 是减数分的最长时期。

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

这些结构对减数分 1 的下一步细胞分过程至关重要。

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

减数分 2 的四个主要步骤是：前期 2、中期 2、后期 2 和末期 2。
