WebSummary. Meiosis is a type of cell division that starts with a diploid, 2 n cell. The process includes two chromosome divisions and produces four haploid, n cells. The haploid cells are genetically different from each other due to crossing over in Prophase I and independent assortment in Anaphase I.
