Question
An individual with genotype I^A I^B will have which blood group?
Correct Answer
Option A is the correct answer.
Detailed Explanation
In the ABO blood group system, the I^A and I^B alleles are codominant. An individual with both alleles (I^A I^B) expresses both A and B antigens on their red blood cells, resulting in blood type AB.
Hint
Codominance of both alleles results in the AB phenotype.
