【植】单倍无配子生殖, 减数分裂的真无配子生殖

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。

Reproduction without meiosis or formation of gametes.

无配生殖，无融合生殖无须减数分裂或形成配子的繁殖

Gametes may develop without fertilization, or meiosis may substantially precede gamete formation.

配子不经过受精也可能发育，若减数分裂先于配子形成，配子也可能发育。

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）。

Such a gamete may be produced by tetraploid tissues, or it may be the result of faulty meiosis.

这样的配子可能是通过四倍体组织或者是错误的减数分裂产生的。

Meiosis, which occurs only in the formation of gametes, is a specialized form of cell division.

仅仅发生在配子形成中的减数分裂是一种特殊形式的有丝分裂。
