Sagot :

Answer:

Meiosis is a type of cell division that produces gametes, which we commonly call the sperm and egg. The steps of meiosis can be remembered using the mnemonic PMAT, which stands for prophase, metaphase, anaphase and telophase.

Explanation:

Meiosis is important because it ensures that all organisms produced via reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
