The occurrence of large or small beak size among seed crackers in the absence of medium sized beaks is an example of

1) directional selection

2) disruptive selection

3) normal distribution

4) stabilizing selection

2) disruptive selection

Explanation:

Disruptive selection is a type of natural selection that acts against less fit heterozygotes. The disruptive selection can be represented by a decrease in the variance of a trait. In this case, the disruptive selection eliminates the medium-sized beaks, thereby favoring the extreme phenotypes in an interbreeding population.
