Iguanas are living in a relatively dry habitat. Imagine a change in the Indiana's habitat from dry land to aquatic. Based on the generation 1 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.
The dominant allele will decrease while the recessive will increase in the gene pool. The dominant allele represents non-webbed feet. Surviving in an aquatic environment will favor the iguanas with webbed feet, so natural selection is occurring.
