Results of crossing-over If crossing-over occurs between a homologous pair of chromosomes during meiosis, what will be present in the gametes? Multiple Choice All chromatids will be recombinant. All chromatids will have the parental combinations of alleles. Some chromatids will have duplicated sections of material, and some chromatids will have missing sections of material Some chromatids will have parental combinations of alleles, and some chromatids will be recombinant. Crossing-over truths What statement about crossing-over is true? Multiple Choice It occurs only in males. It occurs only in some chromosomes. It occurs during meiosis I and meiosis I. It results in reduced genetic variation among gametes None of the answer choices are correct
