Question

Which is a correct statement about mutations?

A. Mutations increase variety in a population.
B. Mutations decrease variety in the population.
C. Mutations ensure alleles never change.
D. Mutations are always bad.

Answer 1

The correct statement about mutations is that they increase variety in a population. Mutations can be beneficial, neutral, or harmful, and are key to the genetic diversity that drives evolutionary change. So the correct answer is Option A.

Step-by-step explanation:

The correct statement about mutations is: A. Mutations increase variety in a population. Mutations are changes to an organism's DNA and are an important driver of diversity in populations. Mutations can lead to a variety of outcomes such as being beneficial, neutral, or harmful. Beneficial mutations spread through the population because they may impart a selective advantage to those who have them. Most mutations are actually neutral, and do not affect an organism's ability to survive or reproduce. Over time, these changes can accumulate, leading to the genetic diversity that fuels evolution.
