Question

Iguanas are living in a relatively dry habitat. Imagine a change in the iguana's habitat from dry land to aquatic. Based on the Generation I allelic frequencies, we can assume only a small percentage of iguanas had webbed feet. Predict what should happen to the allelic frequencies within the iguana population over time.

Answer 1

Due to Natural Selection, it is likely that the allelic frequency would change to favor iguanas with webbed feet. Those animals with webbed feet would have an easier time navigating their environment, which gives them an advantage over those that do not. Hope this helped!
