Answer 1

Mutations affect protein synthesis which impacts the way traits are expressed.

Reason: A mutation changes the DNA sequence, which can change the mRNA and the protein made. Altered proteins can change an organism's traits, and if the mutation is in a gamete (or germ line), it can be passed to offspring, creating inheritable genetic variation.
