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

当两个的细胞膜破，色体飞舞，嘣，你正式有了一个二倍体合子，它几乎立即开始有丝分。

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.

与此同，精子分离的细胞膨胀到来大小的五倍，形成雄，这是包含每个配子遗传信息的两种始细胞之一。

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，从卵子的细胞形成，然后两者开始相互接近，在两者之间沿着蛋白质支架或有丝分纺锤体拉动。
