Question

When considering multi-cellular organisms, what kind of genetic changes will not impact evolution?

Answer 1

Genetic mutations that do not affect fitness will not impact evolution.

Explanation:

Genetic mutations that will not impact evolution must not affect the fitness of the members of the population. Fitness refers to the ability to produce viable offspring. The more viable offspring produced, the more fit the parents are, because their genes are being passed on to the next generation. As long as fitness doesn't change, the population will remain stable.
