Crossing Over - Definition and Functions Biology …

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. WebCrossing over.
