Meiosis is the cell division type that occurs in sexual cells. This process consists of eight steps Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and Telophase II. During the first four stages chromatids exchange DNA among themselves, creating recombinant chromosomes (chromosomes that have a fragment of a different origin). During the last two phases, chromosomes are separated in chromatids, and each cell produced after Telophase II is haploid, that is, it has one chromosome set.
