Question

If the $F_1$ hybrid exhibits a new phenotype that appears as a “blend” of the dominant and recessive phenotypes, it is ___.

• A. Codominance
• B. Incomplete dominance
• C. Complete dominance
• D. Recessive dominance

Answer 1

The correct option is B

Incomplete dominance

In a monohybrid cross, if the $F_1$ hybrid exhibits a new phenotype that seems intermediate between those of parents, and yet, does not completely resemble either of them, it is a case of incomplete dominance.
Codominance is when both the traits are expressed fully, also leading to a new phenotype, but the phenotype does not seem like an intermediate of the two traits.
