Challenge Problems
Push your limits with advanced challenges
If a plant species has a gene pool dominated by allele A, how might a sudden mutation introducing allele a impact future generations? Consider both natural and sexual selection in your response.
💡 Hint: Think about how traits help or hinder survival.
Analyze how genetic drift can lead to changes in allele frequencies in a small population of butterflies isolated on an island. Discuss the potential long-term implications for the butterflies' adaptability.
💡 Hint: Consider how chance events can disproportionately affect smaller groups.
