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.
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!
Hypomorphic Alleles
: A change that reduces, however, doesn't dispense with a gene's usefulness is hypomorphic. A progressively extreme condition, amorphic transformation, dispenses with the gene's capacity.
The great analyses characterizing hypomorphic alleles go back to the 1930s. Herman Miller, who won a Nobel Prize for finding that radioactivity causes changes, considered the eyeshade of organic product flies. These flies typically have red eyes, yet freak assortments can have white or apricot-hued eyes. The allele liable for various natural product fly-eye hues is known as the white allele, with the contraction "w."
