Question

Quizplus · Accepted Answer

Mitosis is a process of cell division that produces genetically identical daughter cells, so it does not create any heritable variation among individuals. In contrast, mutation, crossing over, independent assortment, and fertilization are all sources of heritable variation. Mutation is a random change in DNA sequence that creates new alleles; crossing over during meiosis shuffles alleles between homologous chromosomes; independent assortment of chromosomes during meiosis produces gametes with different combinations of maternal and paternal chromosomes; fertilization combines gametes from two different individuals to create a unique diploid zygote with a new combination of alleles.
