减数分裂图谱
Visión general de la meiosis. En la interfase se duplica el material genético. En meiosis I los cromosomas homólogos se reparten en dos células hijas, se produce el fenómeno de entrecruzamiento. En meiosis II, al igual que en una mitosis, cada cromátida migra hacia un polo. El resultado son 4 células hijas haploides (n).
Meiosis. Se divide en dos etapas. Meiosis I o fase reductiva: su principal característica es que el material genético de las células hijas es la mitad (n) del de las células progenitoras (2n). Meiosis II o fase duplicativa: las células resultantes de esta etapa tienen diferente contenido genético que sus células progenitoras (n).

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Meiotic）
In meiosis, the chromosomes duplicate (during interphase) and homologous chromosomes exchange genetic information (chromosomal crossover) before a first division, called meiosis I. The daughter cells divide again in meiosis II, splitting up sister chromatids to form haploid gametes. Male and female gametes fuse during fertilization, creating a diploid cell with a complete set of paired chromosomes.
A video of meiosis I in a crane fly spermatocyte, played back at 120× the recorded speed.
Gametic life cycle.
Zygotic life cycle.

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.
