Question

Quizplus · Accepted Answer

Individuals with type O blood (genotype ii) are considered universal donors because their blood can be donated to recipients of any ABO blood type (A, B, AB, or O) without causing adverse reactions related to ABO blood group incompatibility. This is because type O blood lacks both A and B antigens on the red blood cells, preventing the immune response that would occur if these antigens were present and recognized as foreign by the recipient's immune system.
