PATHOLOGY

Detailed explanation-1: -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-2: -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-3: -The somatic cell cycles discussed so far in this chapter result in diploid daughter cells with identical genetic complements. Meiosis, in contrast, is a specialized kind of cell cycle that reduces the chromosome number by half, resulting in the production of haploid daughter cells.

Detailed explanation-4: -Somatic cells-that is, the cells in your body that aren’t sex cells-do this via a process called mitosis. New sex cells, or gametes, are produced via a different process, called meiosis.

Detailed explanation-5: -An egg cell in females or sperm cell in males. Each mature sex cell contains 23 chromosomes. When an egg combines with sperm, the fertilized egg normally contains a total of 46 chromosomes. Also called gamete and reproductive cell.
