Crossing over between homologous chromosomes. Consider a cell … WebCrossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I. By meiosis II, only sister chromatids remain and homologous chromosomes have been moved to separate cells. Recall that the point of crossing over is to increase genetic diversity. WebIf crossing over occurs between a homologous pair of chromosomes during Meiosis, what will be present in the gametes?
