0
disruptive; two peaks at either end of the graph with a dip in the middle

Answer 1

The scenario you described is an example of disruptive selection. In this type of selection, individuals at both extremes of a trait (in this case, fur color: light brown and dark brown) have higher fitness compared to those with an average trait (medium brown). As a result, this can lead to a distribution curve that has two peaks, one for each extreme trait and a dip in the middle.

So the correct answer is:

O disruptive; two peaks at either end of the graph with a dip in the middle.
