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

Answer 1

directional selection; the curve would shift to the right

As female reindeer in this population give birth to larger offspring over generations, this indicates directional selection favoring larger birth sizes. The distribution curve for this trait would shift to the right, showing an increase in the average size of offspring being born.
