Answer 2

A population of salmon with different skin colors that attract mates.

Step-by-step explanation:

This is because the salmon have various skin colors to attract mates, so in natural selection, breeding picks out the most successful colors. For example, a gene that possesses a bright blue color on a salmon attracts females more than a gene that possesses a darker blue color. In breeding, natural selection will occur and there will begin to be more male fish with a bright blue color since they are more successful in breeding, than a darker blue color.
