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

减 2减 2 是减的第二次，通常涉及相等的离，或姐妹染色单体的离。

The answer lies within the amazing process of meiosis.

答案就在惊人的减中。

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

然后是配子减，因它们（配子）是不同的。

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

细胞有两种类型：有丝和减。

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

第一次细胞，即第一次减后，配对的同源染色体离。

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

在减中，一个细胞两次，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——它们卡在减的第一阶段。

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

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

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

减的不同阶段是：间期，减 1，胞质 1，减 2，胞质 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。

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

然后它们快速通减 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，也就是第二次减后，每个染色体的姐妹染色单体离。

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一期，形成两个较小的单倍体细胞，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当染色体到达两极时，第一次减有效地结束。

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.

与有丝相似，细胞在进入减之前也经历了间期、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，在减中， 即产生配子 [3] 的中，会发生染色体交叉。

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

减 1 按以下步骤进行：前期 1前期 1 通常是减的最长时期。

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

这些结构对减 1 的下一步细胞至关重要。

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

减 2 的四个主要步骤是：前期 2、中期 2、后期 2 和末期 2。
