If evolution is based upon there being genetic diversity between generations, how does the lack of genetic differences existing between daughter cells created via mitosis impact the theory of evolution

See the answer below

Explanation:

If evolution is based upon genetic diversity, it means that evolution in organisms that only reproduce by mitotic division will depend largely on the frequency of random mutation of genes.

The only way that genetic diversity can occur between daughter cells formed from mitosis is if mutation takes place. Mutation general means a sudden change to the gene sequence of an organism.

Without mutation, evolution in mitotic organisms will be non-existence because there are no new genes or alleles being introduced into the gene pool.
