Quizplus · Accepted Answer

The Bombay phenotype results in a lack of expression of the H antigen, which is required to produce A, B, and AB blood groups. Since this individual does not have the H antigen, they will appear to be blood type O, which is characterized by the absence of A and B antigens on the surface of red blood cells.
