The three types of polygenic selection graphs are:
1. Stabilizing selection: In this type of selection, individuals with intermediate phenotypes have higher fitness compared to those with extreme phenotypes.
2. Directional selection: In this type of selection, individuals with one extreme phenotype have higher fitness compared to those with the other extreme phenotype.
3. Disruptive selection: In this type of selection, individuals with extreme phenotypes have higher fitness compared to those with intermediate phenotypes.
In the case of a rabbit population, the type of selection most likely to lead to a shift toward darker fur would be directional selection. If darker fur provides a survival advantage in the rabbit population (e.g. by providing better camouflage in their environment), then individuals with darker fur would have higher fitness and would be more likely to survive and reproduce, leading to a shift towards darker fur in the population.
