In the Southern United States, a forest ecosystem serves as a habitat for a frog species that is dark green in color. A highway is built, fragmenting this habitat, and after many years the frogs on the west side of the highway appear to be a much lighter shade of green. Describe an experiment that would determine whether allopatric speciation has occurred. Be sure your answer includes the data that would be collected and shows how analyzing this data would help reach a conclusion.
