WebAll body cells, except those set aside for sexual reproduction, are diploid cells. Cells used for sexual reproduction are haploid cells and include the male testes to form sperm and female ovaries to form eggs. During the formation of the gametes, the process of meiosis cuts the chromosome number in half and the sex cells go from diploid to ... 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.
