WebbThis pair of chromosomes are known as homologous chromosomes. ♦ Meiosis can be divided in two stages: meiosis I and meiosis II. It is in the prophase of meiosis I that crossing over of the chromosomes takes place, and the homologous chromosomes are separated into two daughter cells. In meiosis II, the sister chromatids are pulled apart … Webb5 nov. 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.
