Question
Over generations, female reindeer in a Finnish population give birth to larger offspring. Which type of selection is occurring, and how would a distribution curve for this trait change over time?(1 point)
Responses
directional selection; the curve would shift to the left
directional selection; the curve would shift to the left
stabilizing selection; the curve would become shorter in the middle
stabilizing selection; the curve would become shorter in the middle
stabilizing selection; the curve would become taller in the middle
stabilizing selection; the curve would become taller in the middle
directional selection; the curve would shift to the right
1 answer
The correct response is:
directional selection; the curve would shift to the right.
This is because directional selection occurs when one extreme of a trait is favored over the other, leading to an increase in the average size of the offspring (in this case, larger size). Over time, the distribution curve would shift to the right to reflect this change.
