Question

What human traits are codominant?

Answer 1

Codominant:

1. Codominance is the condition where both alleles are equally expressed in a phenotype.
2. ABO blood group inheritance shows codominance.
3. The gene determining the blood group is present in three allelic forms I^A, I^B, and i. I^A and I^B are codominant over i.
4. When I^A and I^B are present together, both the genes are expressed phenotypically with the blood group AB.
5. It is also an example of multiple alleles.
