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。

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

减数分裂 2 最终结果是产生 4 个单胞，n 条染色；(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 按以步骤进行：前期 1前期 1 通常是减数分裂最时期。

The answer lies within the amazing process of meiosis.

答案就在惊人减数分裂过程中。

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 步胞分裂过程至关重要。

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

第次胞分裂，即第次减数分裂后，配对同源染色分离。

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

减数分裂 2 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.

在减数分裂过程中，个胞分裂两次，形成四个子胞。

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

第二次胞分裂，也就是第二次减数分裂后，每个染色姐妹染色单分离。

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 是减数分裂第二次分裂，通常涉及相等分离，或姐妹染色单分离。

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

简而言之，在减数分裂过程中， 即产生配子 [3] 过程中，会发生染色交叉。

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，并且在卵泡期向黄期转换时候等待受精。

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次减数分裂，而个人生中大概只有400个初级卵母胞可以做到。

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

第阶段从婴儿期到青春期，初级卵母胞还停留在第次减数分裂前期。

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

女性生殖胞中，X染色姐妹染色单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.

这使得优势卵泡里初级卵母胞最终完成第次减数分裂，变成了有23条染色次级卵母胞。

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

减数分裂是个分裂过程，单个胞分裂两次，产生四个胞，其中包含半原始遗传信息。

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

正常配子包含23条染色，其中有条X或Y性染色，由亲代生殖胞减数分裂产生。

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.

不分离意味着染色没有分开，所以在减数分裂后形成两个胞中，个拥有2条染色，而另个条都没有。
