Detailed explanation-1: -Sex cells are formed through a particular kind of cell division called meiosis. Unlike in normal cell division (mitosis), the genetic material of the original (parent) cell is divided up twice. As in most other cells in the body, the nucleus of the original cell contains the person’s full set 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: -Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell division that produces sex cells for reproduction. The two processes were discovered by different scientists.

Detailed explanation-4: -Meiosis occurs only in gametes (i.e. sex cells) and the end results are four genetically unique haploid daughter cells per parent cell.

Detailed explanation-5: -Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
