During which phase does crossing over occur
WebApr 21, 2024 · Crossing over (recombination) only occurs during Prophase 1 of Meiosis because at this point homologous chromosomes line up at the centre of the cell. However, after meiosis 1, the newly formed cells consist of single chromosomes, instead of homologous chromosomes. Therefore, crossing over cannot occur after meiosis 1. … WebApr 5, 2024 · Weegy: Crossing over occurs during Prophase I of meiosis.
