Question

In a species of snail, dark-shelled individuals are better hidden from bird predators in the shady forest, while light-shelled individuals are better hidden in well-lit brushy edge areas. If there were no areas of intermediate brightness in this habitat, which type of selection would act on shell color in these snails?

a. stabilizing selection
b. directional selection
c. disruptive selection

Answer 1

c. disruptive selection

Step-by-step explanation:

Disruptive selection is the changes in population genetics favouring extreme values for a trait over intermediate ones.

It's also called diversifying selection as it cause a population to become reproductively distinct from the parent population.
