Under both the handicap principle and the good genes hypothesis, the male trait functions as:
AA method of food storage
BAn honest quality signal
CA random genetic accident
DA form of camouflage
Answer & Solution
Correct answer: B. An honest quality signal
1. Two hypotheses converge on the same interpretation of ornaments.
2. The good genes hypothesis links ornaments to metabolism and disease resistance.
3. In both the handicap principle and the good genes hypothesis, the trait is an honest signal.
4. It signals the males' quality.
5. That gives females a way to find the fittest mates.
