An observable trait in a species of frog is controlled by a single gene. The gene has only two alleles, F and f, and F shows complete dominance over f. A predator is introduced into a population of 400 frogs, of which 100 are homozygous recessive. Describe a graph that would show the frequency of F and f over time, if the homozygous recessive frogs are better able to hide from the predator. Be sure your answer describes the shape of the graph and labels that would need to be included.

Simply put if the recessive trait provides better camouflage then over time their population will increase showing an increase in their graphs curve whereas the Dominant trait frogs will decrease in population so there curve will go down.

I hope you can use this information to make the graph yourself.
