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. WebApr 11, 2024 · Crossing over is a cellular process that happens during meiosis when chromosomes of the same type are lined up.

WebHowever, this is biology so there is a caveat: the phenomenon of crossing over helps to shuffle the alleles for genes located on the same chromosome. A crossover event between the locations of two genes on a chromosome results in genetic recombination, or new combinations of alleles on a chromosome. 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.
