WebSep 21, 2024 · Crossing over is a form of gene recombination. Gene recombination occurs when genetic material is exchanged between either different chromosomes or other regions within the same chromosome.... WebDuring crossing over, DNA is exchanged between two nonsister chromatids of a homologous pair of chromosomes. The nonsister chromatids are both broken in the same places, removing an entire section from each. The section in one nonsister chromatid is swapped for the same section in the other nonsister chromatid. Crossing over produces … WebCrossover occurs between non-sister chromatids of homologous chromosomes. The result is an exchange of genetic material between homologous chromosomes. The chromosomes that have a mixture of maternal and paternal sequence are called recombinant and the chromosomes that are completely paternal or maternal are called non-recombinant. crystal falls tx
