Meiosis is a type of cell division that takes place in the reproductive cells. Their are two main types of reproductive cells: eggs, or female gametes, found in females; and sperm, or male gametes, found in males.

One of the main purposes of meiosis is to produce haploid gametes. During meiosis from one parent cell, four daughter cells are formed. Since four daughter cells are haploid, meiosis is also known as reductional division. Genetic diversity among individuals of the same species is due to meiosis. Genetic diversity helps organisms to survive in the habitat in which they live.

Meiosis takes place twice in living organisms, first during fertilization. During fertilization, a haploid sperm and haploid egg fuse together to form a diploid zygote. During fertilization, crossing over or recombination takes place between paternal chromosomes and maternal chromosomes present in the egg and sperm. Second meiosis takes place at the time of gamete formation.

Spermatogenesis takes in the male reproductive system, and sperm, or male gametes, are formed by meiosis. Oogenesis takes place in the female reproductive system, and haploid eggs are formed by meiosis.

Meiosis is completed in two main stages: meiosis I and meiosis II. Meiosis I is the reduction division, and in meiosis II, duplicate chromosomes are separated among four haploid cells.
