WebWhat is the benefit of meiosis when compared to asexual reproduction? Meiosis is important to sexual reproduction, because through events like crossing over during prophase 1 (the swapping of genetic material between sister chromatids after a process of pairing called synapsis, the exchange sites are called chiasmus) and independent … WebCrossing over produces recombinant chromosomes, individual chromosomes that carry genes (DNA) derived from two different parents. In meiosis in humans, an average of one to three crossover events occur per chromosome pair, depending on the size of the chromosomes and the position of their centromeres. Describe how crossing over works. 1.
