At fertilization, when the haploid gametes fuse, the diploid number of chromosomes is restored.
受精过程中，单倍体配子融合，恢复了二倍体的染色体数目。
Gametes are usually haploid, so fusion of gametes results in the uncleus of the zygote having the diploid number of chromosomes.
配子通常是单倍体，因此发生结合的结果使得受精卵的核中有双倍的染色体。
Generally meiosis occurs before gamete formation, resulting in the gametes being haploid (having half the normal number of chromosomes).
在配子形成前通常会发生减数分裂，产生单倍体的配子。
A gamete containing a diploid number of chromosomes, rather than the usual haploid number.
2一个包含二倍体数目染色体而不是通常单倍体数目染色体的配子。

The results show that there are around 600 bands in the haploid set of the late prophase and 287 bands in the metaphase chromosomes, while prometaphase and early metaphase chromosomes have intermediate numbers of bands. High resolution idiograms for G-banded prometaphase and metaphase chromosomes are drawn.
结果表明，晚前期染色体的带数大约有600条带，中中期有287条带，而前中期和早中期染色体的带数则介于上两者之间。
