Question

When the heterozygous genotype shows both distinct phenotypes, the type of dominance can be described as: a. X-linked dominanceb. Codominancec. Polygenic Dominantd. Complete dominancee. incomplete Dominance

Answer 1

When the heterozygous expresses both phenotypes, we can talk of codominance.

This is what happens in blood types, where a person with an allele A and an allele B expresses both the antigen A and antigen B on the surface of their cell blood.

This means b. Codominance is the right answer.
