1 connection between mutations and reproduction

Answers

Answer:

An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation. Without mutation, evolution could not occur.

Explanation:

mutations affect reproduction. if the mutation has a deleterious affect on the phenotype of the offspring the mutation is a “genetic disorder”
