If a physical trait does not affect an organism’s survival or reproductive success in any way, what is the expected effect of natural selection on this trait?

A. Natural selection will rapidly eliminate the trait from the population.
B. Natural selection will cause the trait to become dominant.
C. Natural selection will have no direct effect on the frequency of the trait.
✓
D. Natural selection will force the trait to mutate into a functional structure.

📝 Explanation

Natural selection only acts on traits that influence differential reproductive success. If a trait is completely neutral with respect to fitness, natural selection does not influence it directly.

📖 Additional Information

  • Natural selection will rapidly eliminate the trait from the population.
  • Natural selection will cause the trait to become dominant.
  • Natural selection will have no direct effect on the frequency of the trait.
  • Natural selection will force the trait to mutate into a functional structure.

Natural selection only acts on traits that influence differential reproductive success. If a trait is completely neutral with respect to fitness, natural selection does not influence it directly.
