Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
____ forms sperm and egg cells.
A
mitosis
B
meiosis
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Detailed explanation-2: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).

Detailed explanation-3: -Spermatogenesis is the process of sperm cell development. Rounded immature sperm cells undergo successive mitotic and meiotic divisions (spermatocytogenesis) and a metamorphic change (spermiogenesis) to produce spermatozoa.

Detailed explanation-4: -Both the egg and sperm cells are produced by Meiosis, which is a special type of cell division, where the cells only have half the number of chromosomes, one from each pair. When the process of Meiosis is complete, 4 cells are formed = eggs or sperm.
