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 is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-3: -Sexual reproduction involves two parents. As you can see from Figure below, in sexual reproduction, parents produce reproductive cells-called gametes-that unite to form an offspring. Gametes are haploid cells.

Detailed explanation-4: -They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.

Detailed explanation-5: -Sexual reproduction uses a type of cell division called meiosis, which creates gametes, such as sperm and egg cells. The process of meiosis happens in the male and female reproductive organs.
