1. Meiosis
The process in which a single diploid cell becomes four haploid cells in two consecutive divisions of the nucleus of an eukaryotic cell. In multicellular organisms this occurs only in the progenitors of sex cells and never in somatic cells.

2. Meiosis
Cell division in which the chromosomes replicate, followed by two nuclear divisions. Each of the resulting gametes (in animals, spores in plants) receives a haploid set of chromosomes. Reduction/division by which ploidy, the number of sets of homologous chromosomes , is reduced in the formation of haploid cells that become gametes (or gametophytes in plants).
