What is the key difference between incomplete dominance and codominance?
A) In incomplete dominance, the recessive allele cannot be detected; in codominance, the expression of the recessive allele is apparent.
B) In incomplete dominance, it is possible to detect the expression of a recessive allele; in codominance, both alleles contribute equally to the phenotype.
C) In codominance, it is possible to detect the expression of a recessive allele; in incomplete dominance, both alleles contribute equally to the phenotype.
D) In incomplete dominance, it is possible to detect the expression of the dominant allele; in codominance, two different genes contribute to multiple phenotypes.
E) The two terms are synonymous.
