Over generations, female reindeer in a Finnish population give birth to larger offspring. Which type of

Question

selection is occurring, and how would a distribution curve for this trait change over time? (1 point)
O stabilizing selection; the curve would become taller in the middle
O directional selection; the curve would shift to the left
O directional selection; the curve would shift to the right
O
stabilizing selection; the curve would become shorter in the middle

Answer 1

The correct answer is: O directional selection; the curve would shift to the right.

Directional selection occurs when individuals with a certain trait (in this case, larger offspring) have a reproductive advantage. Over generations, this would lead to an increase in the frequency of larger offspring, causing the distribution curve to shift toward the larger end (to the right).
