Quizplus · Accepted Answer

The ABO blood types are an example of codominance, as both the A and B alleles are expressed in individuals with AB blood type. This means that neither allele is dominant or recessive, and both are expressed equally. The O allele is considered recessive to both A and B, but even individuals with the O allele express it in their blood type as the absence of A and/or B antigens.
