Which of the following inheritance patterns is matched with an inaccurate molecular basis?

A. Incomplete dominance: The protein produced by a wild-type allele affects the phenotype in a concentration-dependent manner. B. Codominance: Two proteins are produced in heterozygotes. C. Sex-influenced: Hormones alter the expression of proteins encoded by dominant and recessive alleles. D. X-linked: Hemizygotes with the recessive allele do not make a functional protein, but heterozygotes do. E. Simple Mendelian inheritance: The protein produced by a single allele cannot produce the dominant phenotype.
