HELPP !!! If a recessive trait is beneficial to an animal, what happens to the trait's proportion in the population?

It becomes more common
It becomes less common
It doesn't change much

It becomes more common

Explanation:

Even if the trait is recessive if it is beneficial to a population then it will become more common because those with the trait are more likely to survive. For example, if a population of beetles lives on green grass and the dominant trait is for the beetles to be black and the recessive trait is green then the green ones will survive because the black beetles will be eaten first.
