Definition: Meiosis Is the type of division of cell nuclei that occurs specifically to produce the gametes –which are mature sex cells, specifically the ovum in the female and the spermatozoon in the male- that are necessary for sexual reproduction.
Context: After the germ cell's last mitotic division, a period of DNA synthesis occurs, so that the cell initiating meiosis doubles the amount of DNA in its nucleus. In this state, each chromosome consists of two sister chromatids attached at a common kinetochore.
Expression: contributes to normal meiosis
Notes: The complete production of gametes, including both the cell division stage and the subsequent maturing of the gametes is called gametogenesis.
