If a population has a useful heritable variation what is more likely during natural selection?
Answer and explanation
Correct answer: That variation may become more common over generations
The governing concept is natural selection acting on heritable variation. If a variation improves survival or reproductive success in a particular environment, individuals carrying it may leave more offspring. Because the variation can be inherited, its frequency may increase over several generations. Option A is correct, but this is a tendency rather than a guarantee. B is unjustified, C denies heredity, and D confuses an inherited trait with an acquired skill.
