How does crossing over shuffle alleles

WebCrossing over shuffles genes between non-homologous chromosomes. During meiosis, cells arrange their alleles so that beneficial alleles are passed on together. Without crossing over, offspring would be genetically identical to parents. New combinations of alleles arise from the random events of crossing over, independent Show transcribed image text WebTwo chromosomes that have the same gene sequence but may have different alleles of those genes Crossing over The exchange of genetic material between homologous …

WebBy 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. If crossing over did not occur until sometime during meiosis II, sister chromatids, which are identical, would be exchanging alleles.
