Meiosis occurs in the ovaries and testes of animals, and the ovaries and anthers of flowering plants.

Meiosis has two important roles in biology:

1.      It results in haploid cells, which are necessary to maintain the diploid number after fertilisation.

2.      It helps to create genetic variation among offspring.

Gamete production by meiosis:

1.     The DNA replicates so there are two identical copies of each chromosome, called chromatids.

2.     The DNA condenses to form double armed chromosomes, made from two sister chromatids.
