In a population of Mendel's garden peas, the frequency of dominant yellow-flowered plants is 50%. The population is in Hardy-Weinberg equilibrium. From this information alone, can you determine the allele frequencies (A = p and a = q)? Why or why not?
Fill in the blank with the appropriate word.
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.
