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

然后是配子减数，为它们（配子）是不同。

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

减数不同阶段是：间期，减数 1，胞质 1，减数 2，胞质 2。

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

细胞有两种类型：有丝和减数。

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

末期 1当染色到达两极时，第一次减数有效地结束。

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

减数 2减数 2 是减数第二次，通涉及相等离，或姐妹染色单离。

The answer lies within the amazing process of meiosis.

答案就在惊人减数过程中。

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

减数 1 按以下步骤进行：前期 1前期 1 通是减数最长时期。

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

这些结构对减数 1 下一步细胞过程至关重要。

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

减数 2 最终结果是产生 4 个单倍细胞，n 条染色；(人类为 23 条)。

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

第一次细胞，即第一次减数后，配对同源染色离。

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

减数 2 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.

（第二次减数后）细胞数量乘以2，最终结果为两个具有额外染色细胞和两个缺少一条染色细胞。

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

在减数过程中，一个细胞两次，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，在减数过程中， 即产生配子 [3] 过程中，会发生染色交叉。

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

第二次细胞，也就是第二次减数后，每个染色姐妹染色单离。

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中期停止，并且在卵泡期向黄期转换时候等待受精。

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

与有丝相似，细胞在进入减数之前也经历了间期、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，而一个人一生中大概只有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染色姐妹染色单在第二次减数时没有离。
