Answer 1

Answer: AB blood type is an example of codominance

Step-by-step explanation:

The AB blood group is inherited as a result of codominance. If a person receives one group A allele from one parent and one group B allele from the other, both the A and B alleles are expressed, and the individual's blood group is AB.
