WebBecause the events that occur during each of the division stages are analogous to the events of mitosis, the same stage names are assigned. However, because there are two … 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.

WebSep 4, 2024 · Meiosis involves two nuclear and cell divisions without interphase in between, starting with one diploid cell and generating four haploid cells. Each division, named meiosis I and meiosis II, has four stages: prophase, metaphase, anaphase, and telophase. These stages are similar to those of mitosis, but there are distinct and important differences.
