Websignificance of crossing over in meiosis - Example. Meiosis is a type of cell division that occurs in sexually reproducing organisms, including animals and plants. One of the key features of meiosis is the process of crossing over, which plays a crucial role in the production of genetically diverse offspring. WebCrossing over occurs only during prophase I. The complex that temporarily forms between homologous chromosomes is only present in prophase I, making this the only opportunity the cell has to move DNA segments between the homologous pair.
