10 Key Differences Between Mitosis and Meiosis

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. WebMeiosis is like taking two different great songs, isolating some of the tracks from each song (the tracks you isolate from each song are the gamete).
