Question

Why do the cells go through meiosis and mitosis?

Answer 1

To replace dead cells and to make you grow?

Answer 2

After mitosis two identical cells are created with the same original number of chromosomes, 46. Haploid cells that are generated through meiosis, such as egg and sperm, only have 23 chromosomes, because, remember, meiosis is a "reduction division." Makes all cells other than gametes.
