Question

In which situation would the heterozygous phenotype be somewhere between (a blending of) the two homozygous phenotypes?

a. codominance
b. incomplete dominance
c. independent assortment
d. multiple alleles

Answer 1

b. incomplete dominance. (codominance isn't a blend, both dominant are expressed, like with type AB in A-B-O blood antigen expression)

Answer 2

b.) incomplete dominance, as this would be a blending of two dominant types while codominance would have both expressed without blending present
