The Process of Meiosis

Meiosis is the nuclear division of diploid cells into haploid cells, which is a necessary step in sexual reproduction.

In meiosis I, the first round of meiosis, homologous chromosomes exchange DNA and the diploid cell is divided into two haploid cells.

During meiosis II, the sister chromatids within the two daughter cells separate, forming four new haploid gametes.

Mitosis and meiosis share some similarities, but also some differences, most of which are observed during meiosis I.
