A population of rabbits lives in a forest. The habitat features many small spaces for hiding. Over many generations, the average size of the rabbits gets smaller and smaller. What type of selection is this?
Natural Selection. The gene of small size has been favored and that is the gene that gets more dominant in the population over generations.
Answer: Directional Selection
Explanation: Directional selection results in a covariance between the trait and fitness and can lead to changes in a trait in a population.
