In a population of birds, it is an advantage to have a small beak to reach insects in crevices and it is also beneficial to have a large beak to crush seeds. It is a disadvantage to have an average beak size. This is an example of

When allele frequencies in a population remain constant, and evolution does not occur, this is referred to as
