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.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 will eventually disappear from the gene pool.
Dark moths had a survival disadvantage in industrial Dorset.
