What role can mutation play in evolution?
Answer and explanation
Correct answer: It can produce new heritable variation
A mutation is a change in genetic material, such as a change in a DNA sequence or chromosome. If it occurs in a reproductive cell and does not prevent survival, it may be inherited by offspring. The resulting variation can be neutral, harmful or beneficial; beneficial inherited variants may be acted on by natural selection. Therefore option A is correct, while the absolute claims in B, C and D are false.
