meiosis (redirected from Telophase I)

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 (only two of the 23 human chromosome pairs are shown, the chromosomes from one parent in blue, those from the other parent in pink).

mei·o·sis (m-ss) n. pl. mei·o·ses (-sz) The special process of cell division in sexually reproducing organisms that results in the formation of gametes, consisting of two nuclear divisions in rapid succession that in turn result in the formation of four gametocytes, each containing half the number of chromosomes that is found in somatic cells. mei·otic (-tk) adj. mei·oti·cal·ly adv.

meiosis light and dark chromosomes indicate chromosomes from two different individuals

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.

Second meiotic division.

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.
