Answer 1

The correct response is:

directional selection; the curve would shift to the right.

In this case, female reindeer are producing larger offspring over generations, indicating that larger offspring are favored. This leads to a shift in the average size of offspring towards the larger end of the scale, which is characteristic of directional selection. As a result, the distribution curve for this trait would shift to the right over time, indicating an increase in the average size of the offspring.
