Question

question 4 of 10
what could be a good effect of a mutation?
a. dna is destroyed.
b. dna does not function properly.
c. less variety in a population.
d. more variety in a population.

Explanation:

Mutations can introduce new genetic variations. These variations can be beneficial as they provide the raw material for evolution. For example, a mutation might give an organism a trait that helps it better survive in its environment. Over time, if this trait is advantageous, it can become more common in the population. Options A (DNA being destroyed) and B (DNA not functioning properly) are negative effects. Option C (less variety) is also incorrect as mutations typically increase genetic variety rather than decrease it. So, more variety in a population (Option D) is a good effect of a mutation.

Answer:

D. More variety in a population.
