Over generation, female reindeer in a finish population, give birth to larger offspring, which type of selection is occurring and how would a distribution curve or this trait change overtime would it be directional selection? The curve would ship to the right or stabilizing selection the curve would become taller in the middle or stabilizing selection. The curve would become shorter in the middle or directional selection. The curve would shift to the left.
In this scenario, the female reindeer in the Finnish population are giving birth to larger offspring over generations. This indicates that there is a selection pressure favoring larger offspring, suggesting that directional selection is occurring.
Directional selection would cause the distribution curve for this trait to shift to the right over time. As more and more larger offspring are favored by natural selection, the average size of the offspring would increase, causing the curve to move to the right.
Therefore, in this case, the curve would shift to the right, indicating directional selection.
