PATHOLOGY

Detailed explanation-1: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg). The development of a new progeny organism is then initiated by the fusion of these gametes at fertilization.

Detailed explanation-2: -When a sperm cell fertilizes an egg cell, the resulting cell has a full set of genetic information again. 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.

Detailed explanation-3: -Meiosis is the type of cell division that creates egg and sperm cells.
