mei|o|sis
mei|o|sis1 «my OH sihs», noun, plural -ses «-seez».
1. Biology. the process by which the number of chromosomes in reproductive cells of sexually reproducing organisms is reduced to half the original number, resulting in the production of gametes or spores; reduction division. Meiosis consists essentially of two cell divisions. In the first, the homologous chromosomes separate equally into the two new cells so that each contains the haploid number, or half the diploid number. In the second cell division, the pairs of chromosomes split, one of each kind of chromosome going to the four new cells. Thus each new cell again contains the haploid number of chromosomes.
2. = litotes. (Cf. ↑litotes) Also, miosis.
╂[< New Latin meiosis < Greek meíōsis a lessening < meioûn lessen < meíōn less]
mei|o|sis2 «my OH sihs», noun, plural -ses «-seez».
