减数分裂 Meiosis
（重定向自Reduction division）
减数分裂（英语：meiosis）是生物细胞中染色体数目减半的分裂方式。性细胞分裂时，染色体只复制一次，细胞连续分裂两次，染色体数目减半的一种特殊分裂方式。减数分裂不仅是保证物种染色体数目稳定的机制，同且也是物种适应环境变化不断进化的机制。 例如:植物的有性生殖，大孢子母细胞→大孢子，此阶段需要进行减数分裂。

Meiosis 减数分裂
（重定向自Reduction division）
Meiosis /maɪˈoʊsᵻs/ is a specialized type of cell division that reduces the chromosome number by half. This process occurs in all sexually reproducing single-celled and multicellular eukaryotes, including animals, plants, and fungi. Errors in meiosis resulting in aneuploidy are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities.
