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

O stabilizing selection; the curve would become shorter in the middle
O directional selection; the curve would shift to the left
O directional selection; the curve would shift to the right
• stabilizing selection; the curve would become taller in the middle

Answer 1

The correct type of selection occurring in this scenario is directional selection; the curve would shift to the right. As female reindeer give birth to larger offspring over generations, the average size of the offspring increases, resulting in a shift in the distribution curve toward larger sizes.
