meiosis /mei·o·sis/ (mi-o´sis) cell division occurring in maturation of sex cells, wherein, over two successive cell divisions, each daughter nucleus receives half the number of chromosomes typical of the somatic cells of the species, so that the gametes are haploid.meiot´ic
meiosis [mī·ō′sis] Etymology: Gk, becoming smaller the division of a sex cell as it matures into two and then four haploid cells. The nucleus of each receives one half of the number of chromosomes present in the somatic cells of the species. Also called reduction division. Compare mitosis. See also anaphase, metaphase, oogenesis, prophase, spermatogenesis, telophase. meiotic [mī·ot′ik] , adj. meiosis (mio´sis), n a type of cell division of maturing sex cells that ensures that each daughter cell contains the necessary complement of chromosomes for future embryonic development. meiosis the process of cell division by which reproductive cells (gametes) are formed. There are two successive divisions, meiosis I and meiosis II, in which four daughter cells that have the haploid chromosome number are formed. As in mitosis (somatic cell division), meiosis I and II are each divided into four phases: prophase, metaphase, anaphase and telophase. How to thank TFD for its existence?
