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.
-If the researchers of this study wanted to collect reliable data about natural behavior, which methodology should they choose?

• A)The researchers should collect multiple male and female frogs from each species and study them in a lab environment to determine their normal breeding seasons.
• B)The researchers should study multiple male and female frogs from each species in their natural environments to determine their normal breeding seasons.
• C)The researchers should collect multiple male and female frogs from each species, mix males and females from each species, and study the mixed pairs in a lab environment to determine their normal breeding seasons.
• D)The researchers should study one male and female frog from each species in their natural environments to determine their normal breeding seasons.
