WebMeiosis is “reduction division” whereby the cell divides twice to reduce the chromosome number by half. It results in four cells. It involves two divisions called Meiosis I and Meiosis II. Interphase occurs once, only before Meiosis 1. Before reviewing the stages of meiosis in detail, you need to remind yourself about: WebMeiosis has two cycles of cell division, conveniently called Meiosis I and Meiosis II. Meiosis I halves the number of chromosomes and is also when crossing over happens. Meiosis II … WebLike mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase.
