Arden · Answer 2

B. a butterfly predator sees yellow more easily than it does green, and a population of butterflies includes both phenotypes.

Explanation:

The butterfly population is said to have a genetic variation in the form of yellow and green alleles. The green butterflies have a survival advantage over yellow ones as the former one are less visible to the predator.

The selective advantage of green allele over yellow allele would result in the natural selection of green allele. The green butterflies will reproduce more and would leave more progeny in the population.

Gradually, the population would consist of green butterflies only, that is, the evolution of the population of butterflies having green allele only.
