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-infuenced; 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.
E. Simple Mendelian inheritance; The protein produced by a single allele cannot produce the dominant phenotype.

There are now twice as many fixed differences between A1 and A2, relative to the 50,000 years after vicariant event table. Unlike last time, you find that individuals from A1 cannot reproduce with individuals from A2. Compare the DNA sequences presented above and give the amount of variation expected: ...between two randomly chosen individuals of A1. A. relatively low variation B. moderate variation C. relatively high variation
