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: -During meiosis, a diploid parent cell, which has two copies of each chromosome, undergoes one round of DNA replication followed by two separate cycles of nuclear division to produce four haploid cells. These cells develop into sperm or ova.

Detailed explanation-3: -The resulting cells from meiosis are not genetically identical because of the recombination of genes that occurred during prophase 1. Sex cells in humans are produced by meiosis. In males, all four child cells are sperms while in females, one child cell is an egg and the other 3 are polar bodies.
