Incomplete dominance is the result of a dose effect by the wild-type allele. Imagine that it takes 3 units of pigment to produce a red flower in peonies. If a peony wild-type allele produces 2 units of pigment and a mutant allele produces no pigment, how many units of pigment will be produced by homozygous wild-type, heterozygous, and homozygous mutant peonies, respectively?
a) 4; 2; 0
b) 3; 2; 0
c) 2; 4; 0
d) 0; 4; 2
e) 0; 1; 0
