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: Understanding blood group antigens.
Blood group antigens are specific molecules present on the surface of red blood cells, determining blood types.
These antigens are species-specific, meaning that they are found within a particular species, such as humans.
Step 2: Analysis of options.
- (1) Species specific: Correct. Blood group antigens are specific to a species. In humans, these include ABO and Rh antigens.
- (2) Isospecific: This refers to antigens shared by members of the same species, but not specific to blood groups.
- (3) Autospecific: This term is not commonly used in relation to blood group antigens.
- (4) Organ specific: Antigens are not generally specific to individual organs but rather the species.
Step 3: Conclusion.
Blood group antigens are species-specific, and the correct answer is (1).
