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)

Question

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 taller in the middle
stabilizing selection; the curve would become taller in the middle

stabilizing selection; the curve would become shorter in the middle
stabilizing selection; the curve would become shorter in the middle

directional selection; the curve would shift to the right

Answer 1

The correct response is:

directional selection; the curve would shift to the right.

Directional selection occurs when one extreme of a trait distribution is favored over others, leading to a shift in the overall distribution of that trait. In this case, since female reindeer are giving birth to larger offspring over generations, the distribution of offspring size would shift to the right, indicating an increase in the size of the offspring.
