Meiosis causes a decrease in genetic variation, because of polyploid gametes. Meiosis causes an increase in genetic variation, because of non-disjunction of homologous chromosomes. Meiosis causes an increase in genetic variation, because of non-disjunction of homologous chromosomes. Meiosis causes a decrease in genetic variation, because of the creation of diploid (2N=46) gametes. Meiosis causes a decrease in genetic variation, because of the creation of diploid (2N=46) gametes. Meiosis causes an increase in genetic variation, because of the crossing over of genetic material between homologous chromosomes.

Answer 1
