A)Even in a seemingly clear- cut example of complete dominance,at the protein or enzyme level,one can detect about half the activity or gene product. B)With both incomplete dominance and codominance,one expects heterozygous and homozygous classes to be phenotypically identical. C)An individual won't show incomplete dominance if one allele is a loss of function allele. D)The threshold effect is only seen in incomplete dominance,not in codominance. E)In the threshold effect,one would expect the gain of function mutant to be recessive.
