This would suggest that (Level 2) A. The red-eyed trait is recessive to white eyes. B. The red-eyed trait is dominant to white eyes. C. The red-eyed and white-eyed genes are co-dominant. D. The eye color trait is most likely coded for by multiple genes. E. None of the above. 1.2 Which of the following mutations would be MOST likely to be retained in a species gene pool? (Level 3) A. A mutation resulting in a deleterious change in a cytoskeletal protein structure B. A mutation in an exon of a gene coding for DNA repair C. A mutation in an intron of a gene coding for DNA repair D. Both A and B E. None of the above 1.3 Many cancer cells exhibit aneuploidy, meaning that they (Level 1) A. Proliferate at higher rates than normal cells.
