WebNov 5, 2024 · This is the first step in the process of Meiosis cell division. The Prophase of Meiosis is quite long and more complex than the Prophase of Mitosis. This single substep of Prophase is further subdivided into 5 stages, namely - Leptotene, Zygotene, Pachytene Diplotene, and Diakinesis. These are discussed briefly below.
