NEET BIOLOGY

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: -Meiosis Consists of a Reduction Division and an Equational Division. Two divisions, meiosis I and meiosis II, are required to produce gametes (Figure 3).

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.

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.
