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

然后是配子减数分裂，因为它们（配子）是不同的。

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

减数分裂 2 的最是产生 4 个单倍体细胞，n 条染色体；(人类为 23 条)。

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 通常是减数分裂的最时期。

The answer lies within the amazing process of meiosis.

答案就在惊人的减数分裂中。

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

这些构对减数分裂 1 的下一步细胞分裂关重要。

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，配对的同源染色体分离。

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。

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

在减数分裂中，一个细胞分裂两次，形成四个子细胞。

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

第二次细胞分裂，也就是第二次减数分裂后，每个染色体的姐妹染色单体分离。

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，通常涉及相等的分离，或姐妹染色单体的分离。

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

简而言之，在减数分裂中， 即产生配子 [3] 的中，会发生染色体交叉。

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，并且在卵泡期向黄体期转换的时候等待受精。

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。

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染色体姐妹染色单体在第二次减数分裂时没有分离。

This triggers the primary oocyte within the dominant follicle to finally complete meiosis 1, and turn into a secondary oocyte, which has 23 chromosomes.

这使得优势卵泡里的初级卵母细胞最完成第一次减数分裂，变成了有23条染色体的次级卵母细胞。

Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.

减数分裂是一个分裂，单个细胞分裂两次，产生四个细胞，其中包含一半的原始遗传信息。

Typically a gamete with 23 chromosomes, including one sex chromosome either X or Y, develops when parent germ cells undergo the process of meiosis.

正常的配子包含23条染色体，其中有一条X或Y性染色体，由亲代生殖细胞减数分裂产生。

Nondisjunction means the chromosomes don't split apart - so following meiosis, one resulting sex cell ends up with both chromosomes and the other gets none.

不分离意味着染色体没有分开，所以在减数分裂后形成的两个细胞中，一个拥有2条染色体，而另一个一条都没有。
