 Definition: 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.
  1. The reduction division process by which haploid gametes and spores are formed, consisting of a single duplication of the genetic material followed by two mitotic divisions.
  2. The process of two consecutive cell divisions in the diploid progenitors of sex cells. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes.
  3. the form of cell division occurring in specialized tissues in the testes and ovary that leads to the production of gametes.
