A) At high frequencies, the dominant allele will become codominant.
B) Recessive alleles are weaker than dominant alleles.
C) At low frequencies, recessive alleles are usually in the heterozygous state, and not subject to natural selection.
D) Dominant alleles are passed on all the time, recessive alleles are passed on half the time.
E)  B and D

Well this is a poorly worded question. You should probably write to the side of this question "Dear Professor, You are awful at writing tests. Go back to graduate school". That aside, I would go with B in that there is no phenotypic expression of a the recessive allele in a heterozygous individual. C is technically also sort-of true too except it does not answer the question which alludes that there IS natural selection taking place because the mutation in favorable. I can tell you for sure that it is definitely NOT A, D, or E.
