Imagine three islands, each with a population of frogs. There are approximately 1,100 frogs on Island 1, 400 on Island 2, and 400 on Island 3. Researchers estimate that these populations have been separated for 800 years. Individuals in these populations show variation in markings on their body by shape and color. Frogs on Islands 1 and 2 have circle markings that are either red, blue, or purple. All frogs on Island 3 have yellow triangle markings. The islands recently became a tourist destination, with new passenger boats connecting Island 1 and Island 2, and Island 1 and Island 3 (there is no boat that goes between Island 2 and Island 3). Would a biologist agree or disagree with the following statements? part 1 The current boat routes will decrease the likelihood of a speciation event occurring between the frog populations on Islands 2 and 3 in the future. Question options: Agree Disagree part 2 The observation that all frogs on Island 3 have yellow markings could be a result of genetic drift, but not natural selection Question options: Agree Disagree The observation that all frogs on Island 3 have yellow markings could be explained by natural selection, but not genetic drift. Question options: Agree Disagree
