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

然后是配子减数分裂，们（配子）是不同的。

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。

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

细胞分裂有两种类型：有丝分裂和减数分裂。

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

末期 1当染到达两极时，第一次减数分裂有效地结束。

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

减数分裂 2减数分裂 2 是减数分裂的第二次分裂，通涉及相等的分离，或姐妹染的分离。

The answer lies within the amazing process of meiosis.

答案就在惊人的减数分裂过程中。

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

减数分裂 1 按以下步骤进行：前期 1前期 1 通是减数分裂的最长时期。

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

这些结构对减数分裂 1 的下一步细胞分裂过程至关重要。

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

减数分裂 2 的最终结果是产生 4 个倍细胞，n 条染；(人类 23 条)。

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，配对的同源染分离。

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

减数分裂 2 的四个主要步骤是：前期 2、中期 2、后期 2 和末期 2。

Multiply by two, and the final result is 2 cells with an extra chromosome, and two cells missing a chromosome.

（第二次减数分裂后）细胞数量乘以2，最终结果两个具有额外染的细胞和两个缺少一条染的细胞。

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

在减数分裂过程中，一个细胞分裂两次，形成四个子细胞。

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， 即产生配子 [3] 的过程中，会发生染交叉。

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，每个染的姐妹染分离。

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，并且在卵泡期向黄期转换的时候等待受精。

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

与有丝分裂相似，细胞在进入减数分裂之前也经历了间期、G1、S 和 G2 期。

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，而一个人的一生中大概只有400个初级卵母细胞可以做到。

The first stage lasts from infancy to puberty, and during this stage the primary oocyte remains stuck in the prophase step of meiosis 1.

第一阶段从婴儿期到青春期，初级卵母细胞还停留在第一次减数分裂的前期。

The other option is the sister chromatids of the x chromosome don't separate in meiosis two in the female germ cell.

女性生殖细胞中，X染姐妹染在第二次减数分裂时没有分离。
