Detailed explanation-1: -Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.

Detailed explanation-2: -In meiosis, a single cell divides twice to produce four daughter cells. These daughter cells or sex cells have exactly half the genetic material of normal gametes. Meiosis necessitates two divisions since it produces a haploid cell with half the amount of chromosomes. Thus meiosis occurs twice.

Detailed explanation-3: -There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.

Detailed explanation-4: -Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.

Detailed explanation-5: -During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes. The mechanics of meiosis II is similar to mitosis, except that each dividing cell has only one set of homologous chromosomes.
