The squinting bush brown butterfly uses its eyespots as a defense mechanism against predatory birds. During the selection of mates, females will choose against males that have too large or too small eyespots. This reduces the amount of phenotypic variation.

Which type of natural selection selects against extreme phenotypes?

A

The squinting bush brown butterfly reduces phenotypic variation through directional selection.

B

Selection for the most common phenotype is known as stabilizing selection.

C

Selection against extreme phenotypes is known as marginalization.

D

The squinting bush brown butterfly eliminates extreme phenotypes by the mechanism of mutational selection.

E

Prevention of an increase in phenotypic variation is known as disruptive selection.
