Question

What is the blood group of a person who has neither antigen A nor B but is positive for antigen d

Answer 1

Answer:The blood group of a person who does not have antigen A or B but is positive for antigen D is classified as blood group O positive (O+).

Explanation: In the ABO blood typing system, there are four main blood types: A, B, AB, and O. These blood types are determined by the presence or absence of specific antigens on the surface of red blood cells. Antigens A and B are responsible for blood types A and B, respectively.

 If a person lacks both antigen A and antigen B, they are considered to have blood type O. The positive (+) or negative (-) designation refers to the presence or absence of the Rh antigen, also known as the D antigen. A person who tests positive for the D antigen is Rh-positive.

Therefore, a person who does not have antigen A or B but is positive for the D antigen is classified as blood group O positive (O+).

Answer 2

A person who lacks both antigen A and antigen B but is positive for antigen D belongs to the blood group O positive (O+). In the ABO blood grouping system, there are four main blood types: A, B, AB, and O, based on the presence or absence of antigens A and B on the red blood cells.

Antigen D refers to the Rh factor, which is another important component of blood typing. If an individual has the Rh antigen D, they are considered Rh positive (+), whereas the absence of the antigen D indicates Rh negative (-). Therefore, a person who lacks antigens A and B but has antigen D is classified as O positive (O+).
