PATHOLOGY

Detailed explanation-1: -The formation of sex cells is a central part of human reproduction: In fertilization, an egg cell and a sperm cell combine. These sex cells are also called reproductive cells or gametes. Sperm cells are produced in men’s testicles and egg cells are produced in women’s ovaries.

Detailed explanation-2: -Definition. Germ line refers to the sex cells (eggs and sperm) that sexually reproducing organisms use to pass on their genomes from one generation to the next (parents to offspring). Egg and sperm cells are called germ cells, in contrast to the other cells of the body, which are called somatic cells.

Detailed explanation-3: -When they combine, each sex cell contributes half the number of chromosomes to produce offspring with the correct number of chromosomes.
