Question

A person who lacks agglutinogens A and B would have blood type __________.

- A
-AB
- B
-O

Answer 1

People with blood type O lack both agglutinogens A and B on their erythrocytes.

Step-by-step explanation:

People with blood type O lack both agglutinogens A and B on their erythrocytes. This means that their red blood cells do not have either antigen A or antigen B on their surface. However, they have both anti-A and anti-B antibodies circulating in their blood plasma. Therefore, the correct answer is O.
