In a population of beetles, there are variations of dark green, intermediate colors, and light green. From heavy rains, the dark green background of moss has a lot of growth. The type of beetles that survived this changed selective pressure were the dark green ones. What type of selection is this?

• stabilizing

• directional

• disruptive

• allopatric

White, red, and pink birds migrate to an environment with pink flowers. Only the pink birds survive. What type of selection is this?

• disruptive

• stabilizing

• directional

A type of butterfly that lives in a forest is either red, pink, or white. In the forest, red and white flowers are common, but pink flowers are rare. The red and white butterflies have a higher population density than the pink butterflies. What type of selection is this?

• disruptive

• stabilizing

• directional

• polar
