During meiosis, homologous chromosomes may exchange genetic material during a process called "crossing over."How does this benefit the organism?ACrossing over results in the production of more gametes during meiosis. Having more gametes increases the reproductive fitness of the organismBCrossing over produces additional copies DNA regulatory molecules. Increased cell cycle regulation improves the overall fitness of the organism by reducing the chance of mutationCCrossing over produces new combinations of genes on alleles, increasing genetic variation. Genetic diversity increases the fitness of the populationDCrossing over allows homologous chromosomes to correct errors in their sequences by filling in gaps caused by missing nucleotides. This improves the fitness of the organism by retaining intact genetic sequences
