In negative frequency-dependent selection,
- A
All phenotypes have identical fitness, regardless of frequency
- Bcheck_circle
Rare phenotypes are favored, helping maintain polymorphism
- C
Common phenotypes are favored, eroding polymorphism over time
- D
Rare phenotypes are eliminated, driving the dominant one to fixation
Explanation
A rare prey type is harder for predators to recognize, so it survives better. The favored type changes as it becomes common, maintaining variation.
