Question

Blood group antigens are:

• A. Species specific
• B. Isospecific
• C. Autospecific
• D. Organ specific
• E.

Hint:

Blood group antigens are critical for blood transfusions and organ transplants, as matching them between donor and recipient is vital.

Answer 1

The Correct Option is A

Step 1: Blood Group Antigens Defined.
Blood group antigens are molecules on red blood cells that define blood types. They are species-specific, meaning they are unique to a particular species, like humans.
Step 2: Option Evaluation.
- (1) Species specific: Accurate. Blood group antigens are species-specific (e.g., human ABO and Rh antigens).
- (2) Isospecific: Refers to antigens shared within a species, but not exclusively for blood groups.
- (3) Autospecific: Not a standard term for blood group antigens.
- (4) Organ specific: Antigens are typically species-specific, not organ-specific.
Step 3: Final Determination.
Blood group antigens are species-specific. Option (1) is the correct classification.
