WebMeiosis can be divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II): Meiosis I 1. Interphase: The DNA in the cell is copied resulting in two identical full sets of chromosomes. WebIntroduction: Meiosis is a type of cell division that produces gametes – sperm and egg cells – in sexually reproducing organisms.
