What Is the Key Difference Between Incomplete Dominance and Codominance

question 42

Multiple Choice

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.
