Question

Which situation would most likely result i the greatest change in gene frequency in a population ?

Answer 1

D) A predator eats one phenotype rather than another for a year

Answer 2

Answer:

The most appropriate answer would be option D.

If a predator eats only one type of phenotype that means that the other phenotype must provide some type of survival advantage to the individuals such as camouflage.  

It would result in differential reproduction and thus, natural selection would come into action.

Consequently, the allele frequency of a population would change after numerous generations.
