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数分裂，成两较小的单倍细胞，称为次级精母细胞。

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 单倍细胞，n 条染色；(人类为 23 条)。

The microtubules that make up the spindle network disappear, and a new nuclear membrane surrounds each haploid set.

组成纺锤网络的微管消失，每组单倍周围都有层新的核膜。

These four daughter cells only have half the number of chromosomes than the parent cell; they are haploid.

这细胞的染色数目只有母细胞的半；它们是单倍。

A genome is the haploid set of chromosomes in a gamete, or microorganism, or each cell of a multicellular organism.

基因组是指配、微生物或多细胞生物每细胞中的单倍染色组。

Those are called haploid cells and we have four of those in meiosis.

那些叫做单倍细胞，在减数分裂中我们有这样的细胞。

How do we go from a diploid cell eventually to a haploid cell?

我们是如何从二倍细胞最终变成单倍细胞的？

You'll remember from biology that gametes are haploid cells, meaning that they only have one set of chromosomes, and are formed by meiosis.

你会记得生物学中配是单倍细胞，这意味着它们只有套染色，是由减数分裂成的。

Nuclear envelopes reform and cleavage or cell plate formation eventually produces a total of four daughter cells, each with a haploid set of chromosomes.

核膜的改造和分裂或细胞板的成最终产生细胞，每细胞都有组单倍染色。

And so the cell cycle will take a diploid cell make two diploid cells in mitosis or make four haploid cells in meiosis.

细胞周会将二倍细胞通过有丝分裂产生两二倍细胞，或者通过减数分裂产生单倍细胞。

In meiosis we're going to take a normal diploid cell and we're actually going to make a haploid cell, we're going to make sperm and egg.

在减数分裂过程中， 我们会从正常的二倍细胞开始， 最终制造出单倍细胞，即精和卵。

And so eventually what you get on this side are, instead of having ones that are haploid, you'll actually have some that could even be 4n or 3n or 2n on this side.

因此， 最终在这边得到的，不再是那些单倍的，实际上会有些甚至可以是倍、三倍或二倍的。
