Male gametogenesis is one of the key steps in plant sexual reproduction and is essential for the alternation between the diploid sporophytic phase and haploid gametophytic phase in the life cycle of higher plants.
植物雄配子体发生和发育是有性生殖的关键步骤之一，是高等植物通过有性生殖进行世代交替所必需的。
-
Outcrossing, the second fundamental aspect of sex, is maintained by the advantage of masking mutations and the disadvantage of inbreeding which allows expression of recessive mutations (commonly observed as inbreeding depression).
有性生殖的第二个基本方面是异型杂交。异型杂交是通过掩蔽突变优势和近亲繁殖劣势来维持的。近亲繁殖允许隐性突变的表达。这与查尔斯·达尔文相一致。

sexual reproduction：有性生殖
一般有两种方式,即无性生殖(asexual reproduction)及有性生殖(sexual reproduction). 无性生殖不产生配子,其经由复制、分裂后产生与母细胞相同的个体. 而有性生殖产生两种不同的配子,经由配子结合后产生新个体,有性生殖具有交换遗传物质的特性,
