Answer 2

The occurrence of the large or small beak sizes among the seed crackers is the illustration of disruptive selection.

What is disruptive selection?

It is the kind of natural selection, which is bimodal and favors both the extremes traits within a population. It is a kind of natural selection, which opts against the average individual within a population. This kind of selection would show the phenotypes demonstrating both the extremes, however, exhibit very less individuals in the middle.

A classic example of disruptive selection is the size of the beak of the finches on the Galapagos Islands. As the majority of the seeds found these islands were either small or large, therefore, finches with small and large beaks were favored on those islands.

Thus, the correct answer is option c, that is, disruptive selection.
