Web16 jan. 2024 · Prophase I is composed of five stages. These include: Leptotene: The shortest phase of prophase I is leptotene, which is the prophase’s initial stage. It is a replicated chromosome’s condensation phase. The chromosomes compress, become visible, and condense, allowing for the separation of sister chromatids. Web12 jan. 2016 · Prophase 1 of meiosis is where the crossing-over occur. Explanation: Each of the homologous chromosome line up side by side, forming tetrads. While they lined up, segments of the chromosomes may be exchanged. This process is important as it promotes genetic diversity.
