Explanation-
Meiosis is a type of cell division, which is a characteristic feature of sexually reproducing organisms. It produces reproductive cells called gametes, which possess half number of chromosomes as compared to their parental cells ( which are diploid). Gametes from each parent fuse to form a diploid zygote that develops into an individual.
