Question 2 / 120:  A local snail has 3 phenotypes with the heterozygous individuals showing incomplete dominance. Therefore, individuals with a genotype of BB are brown, Bb are tan, and bb are white. These snails are particularly tasty to the local birds. Due to a recent storm, their current environment only affords camouflage for the tan individuals, because all the brown and white tide pools have been covered by tan sand by the storm. Therefore, the brown and white individuals are seen and eaten more easily by the birds. Which graph below describes this example of selective pressure?
