If an organism has a useful variation but cannot reproduce, why will that variation not increase in the population?

Answer and explanation

Correct answer: Because the trait will not pass to the next generation

Natural selection changes a population only when heritable variation affects survival or reproduction and is transmitted to descendants. A useful trait in an organism that leaves no offspring cannot be inherited by the next generation, so its frequency cannot rise through that organism’s reproduction. Option A is correct. The trait need not be recessive, become a fossil, or dissolve in blood; those statements do not explain population-level inheritance.
