The genetic variation in the population is decreasing due to selective pressure. The genetic variation in the population is increasing due to gene flow. The genetic variation in the population is decreasing due to gene flow.

Answer 1

The genetic variation in the population is decreasing due to selective pressure.

Answer 2
