Identify the reasons why meiosis leads to significant genetic variation while mitosis does not. select the two correct reasons. select the two correct reasons. meiosis results in extensive genetic variation by converting a diploid cell into haploid gametes or spores faster than in mitosis. crossing over happens at a much lower frequency in meiotic cells as compared with mitotic cells. daughter cells resulting from the process of meosis are usually genetically identical. through independent assortment of chromosomes at telophase i of meiosis, daughter cells may contain different sets of maternally and paternally derived chromosomes. crossing over happens at a much higher frequency in meiotic cells as compared with mitotic cells. through independent assortment of chromosomes at anaphase i of meiosis, daughter cells may contain different sets of maternally and paternally derived chromosomes.
