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 and were able to survive. Over many generations, if their habitat remains aquatic, iguanas without webbed feet will disappear from this population. Scientists eventually distinguish two species of iguanas, one that has feet with no webbing that lives on land and another that has webbed feet, living in and around aquatic habitats. What comment can you make about the genetic make-up of the two iguana species?.
