D)there are many possible mutations that lead to white eyes in flies
E)a certain plant can have jagged,rough,or smooth edges on its leaves

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.

A)A mutation in the DNA can be observed at the macroscopic level even if there's no change in phenotype.
B)Each biochemical pathway is governed by one gene.
C)A neutral mutation leads to no discernable phenotype.
D)A neutral mutation leads to a phenotype that can help or hurt the organism depending on the environment.
E)A neutral allele leads to a change in function in a protein that neither harms nor helps an organism.
