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。
Meiosis, which usually precedes spore or, sometimes, gamete formation, halves the chromosome number to produce haploid gametes.
染色体数目减半通常发生在减数分裂产生孢子或往往是合子减数分裂形成单倍体配子时。
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 basic set of chromosomes in a species is the haploid set, usually found in the gametes.
一个物种染色体的基本数目是一个单倍体组,这通常见于配子中。
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(染色体数为正常的一半)。
