question 4

Multiple Choice

Scenario
As part of a semester-long biology field research course, you are studying reproductive barriers among four different frog species. Your goal is to determine what type of reproductive barrier likely causes the gene pools of the four different frog species to be isolated. These four species share common geographic habitats and are both anatomically and gametically compatible. Your research professor gives you the following figure to consider. After studying the figure, answer the questions that follow.
-What can you conclude about the breeding characteristics of these four frog species?

• A)The maximum mating activity of the four frog species at different times reduces and/or removes interbreeding.
• B)Each frog species must find a different place in the pond to breed.
• C)The individual mating activity of the bull frog species reduces and/or removes interbreeding in the other three frog species.
• D)An increase in maximum mating activity of the wood frog species reduces and/or removes interbreeding in the bull frog species.
