Question

In a population of mice individuals with medium brown fur are less likely to be seen by predators, then light brown and dark brown mice what type of selection is this and what would the distribution curve for the mouse population look

A disruptive, a tall, narrow peak in the center of the graph
B disruptive peaks at either end of the graph with a dip in the middle
C stabilizing, a tall, narrow peak in the center of the graph
D stabilizing two peaks at either end of the graph with a dip in the middle

Answer 1

The situation described in the question suggests disruptive selection. Disruptive selection occurs when extreme phenotypes have higher fitness compared to the intermediate phenotype. In this case, the medium brown mice have lower fitness because they are more likely to be seen by predators, while the light brown and dark brown mice have higher fitness due to their better camouflage abilities.

The distribution curve for the mouse population would be bimodal, showing two peaks at either end of the graph (light brown and dark brown mice) with a dip in the middle (medium brown mice). Therefore, the correct answer is B: disruptive peaks at either end of the graph with a dip in the middle.
