Question

What change is observed in a distribution curve for a trait affected by disruptive selection?(1 point) Responses If shifts to the right and the left. If shifts to the right and the left. It shifts to the left. It shifts to the left. It shifts to either the right or the left It shifts to either the right or the left If shifts to the middle.

Answer 1

In disruptive selection, the distribution curve for a trait typically shows a pattern where the extremes of the trait become more common, while the average trait value decreases in frequency. This results in the curve shifting to create two distinct peaks, one on each end of the trait spectrum, rather than a single peak in the middle.

Therefore, the correct response is: **It shifts to either the right or the left** (resulting in the formation of two peaks).
