The process of meiosis increases genetic variation when genetic information is exchanged during crossing-over and when alleles are independently and randomly assorted into daughter cells. which of the following processes also contributes to genetic variation? a. genetic cloning b. cell specialization c. random fertilization d. mitotic divisions

The correct answer is random fertilization.
Together with crossing over and independent assortment, random fertilization represents the way by which sexually reproduction contributes to genetic variation. Random fertilization refers to the random event of fertilization when there is no way in knowing which sperm will fertilise which egg (64 trillion possible combinations of genes that can occur during fertilization). Any sperm cell from the male can fuse with any egg cell from the female.
