Definitions: Meiosis |
MeiosisNoun1. (genetics) cell division that produces reproductive cells in sexually reproducing organisms; the nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants). 2. Understatement for rhetorical effect (especially when expressing an affirmative by negating its contrary); "saying `I was not a little upset' when you mean `I was very upset' is an example of litotes".

Etymology: Meiosis \Mei*o"sis\, noun. [New Latin expression, from the Greek expression, from to make smaller. See Meionite.]. (Websters 1913) |

(From Wikipedia, the free Encyclopedia)
The mechanistic differences between mitosis, which produces somatic cells, and meiosis, is best understood by considering mitosis first. (All jargon used in this article is defined in the article on mitosis.) During a mitotic division, chromosomes are duplicated but remain closely aligned, and these twin copies are called sister chromatids. Note that diploid cells have two sets of homologous chromosomes. DNA replication generates sister chromatids from each chromosome, and in the interval between DNA replication and cell division, the cell bears four copies of each chromosome. At metaphase, sister chromatids align on the mitotic spindle. At anaphase, these sister chromatids separate, each migrating toward an opposite pole of the spindle. The two new cells that result bear one copy of each homologous chromosome.
A meiotic nuclear division consists of two stages, called meiosis I and meiosis II. It starts with a cell in the same state as does a mitotic division. However, the alignment of chromosomes for prophase is different. Homologous chromosomes join into tetrads (so called because each tetrad contains four chromatids), and the tetrads line up on the metaphase plane. During prophase I (the prophase of meiosis I), various phenomena unique to meiosis may occur, such as crossing over. During metaphase I, the tetrads line up on the metaphase plate or equatorial plate. During anaphase I, they are pulled apart into their constituent homologous chromosomes.
Meiosis II is identical to mitosis.

(From Wikipedia, the free Encyclopedia)
Meiosis is a figure of speech which intentionally understates something or implies that it is less in significance, size, than it really is.The hero says his wound is "only a scratch", employing meiosis. W. C. Fields enters a palatial home, glances up at the ceiling two stories above, and says "Nice teepee."

Health | Dr. Hassold explained that cells destined to become sperm or eggs undergo a process known as meiosis. (references) | |
In this process, the 46 chromosomes in the cell separate, ultimately producing two new cells having 23 chromosomes each. Before meiosis is completed, however, chromosomes pair with their corresponding chromosomes and exchange bits of genetic material. (references) | ||
