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: -Homologue pairs separate during a first round of cell division, called meiosis I. Sister chromatids separate during a second round, called meiosis II. Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm).
Detailed explanation-3: -The entire meiosis cell cycle has only one S phase that means the DNA will get replicated only once in the entire meiotic division.
Detailed explanation-4: -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-5: -Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis.
