Can sunlight change the distribution of traits in a population?
(1 point)
Yes, because the environment can factor into the
distribution of traits.
No, because the environment can only change traits in individual organisms.
No, because the environment can only change behaviors.
Yes, because the environment is the only factor that can change traits.
