Question

Explain why mitosis does not produce genetic variation and how meiosis leads to the production of tremendous genetic variation.

Answer 1

Mitosis produces cells that are genetically identical to the parent cell.
Meiosis includes two distinct processes that contribute to the generation of
genetic variation: crossing over shuffles alleles on the same chromosome
into new combinations, whereas the random distribution of maternal and
paternal chromosomes shuffles alleles on different chromosomes into new
combinations.
