PATHOLOGY

Detailed explanation-1: -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-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: -In females, the process of meiosis is called oogenesis, since it produces oocytes and ultimately yields mature ova(eggs).
