question 21 1 pts a species of bird lives in an area where large and small seeds are common, but medium size seeds are not. birds with large beaks are adept at eating large seeds and birds with small beaks are adept at eating small seeds. this population will likely undergo directional selection. disruptive selection. stabilizing selection. artificial selection.

Explanation:

In disruptive selection, extreme phenotypes are favored over intermediate ones. Here, birds with large beaks (for large seeds) and birds with small beaks (for small seeds) are favored as medium - sized seeds are rare. This is an example of disruptive selection as the population will split towards the two extreme beak - size phenotypes.

Answer:

B. disruptive selection
