Question 1
Given a population of mice, some have light fur and some have dark. Suppose an environmental change makes the habitat darker. Predict the changes in fur color over the next generations and why that might happen.
💡 Hint: Think about how the environment interacts with trait visibility and predation.
Question 2
You observe a population of butterflies that exhibit a range of wing patterns. If butterflies with intermediate patterns are more successful in avoiding predators, describe how you would expect the allele frequencies to change over time.
💡 Hint: Focus on how selection affects population traits over time!
