When the membranes of the two pronuclei rupture, chromosomes go flying, and boom, you officially have a diploid zygote, which almost immediately starts mitosis.

当两个原核的细胞膜破裂时，染色体飞舞，嘣，你正式有了一个二倍体合子，它几乎立即开始有裂。

Meanwhile, the sperm's detached nucleus swells up to five times its original size, forming the male pronucleus, one of two sort of proto-nuclei that contain each gamete's genetic information.

此同时，精子离的细胞核膨胀到原来大小的五倍，形成雄性原核，这是包含每个配子遗传信息的两种原始细胞核之一。

The other one, the female pronucleus, takes shape from the nucleus of the ovum, and then the two then start to approach each other, pulled along a protein scaffolding, or mitotic spindle, between the two.

另一个，雌性原核，从卵子的细胞核形成，然后两者开始相互接近，在两者之间沿着蛋白质支架或有裂纺锤体拉动。
