Based on your reading of the article entitled "Regulating Evolution", which of the following is a false statement?

A. Individuals who are resistant to the malaria-causing parasite, Plasmodium vivax, have lost the enhancer that drives expression of the Duffy gene in red blood cells.

B. Drosophila strains that have a yellow body are caused by a mutation within the coding region of the gene, thereby eliminating Yellow protein production throughout the animal.

C. Drosophila strains that have a black spot within the wing blades have gained an enhancer that permits for expression of the Yellow gene within the wing.

D. Stickleback fish that live at the bottom of shallow lakes have lost an enhancer that drives expression of the Pitx1 gene within regions that give rise to the pelvic-fin bud and spines.
