Which of the following statement is INCORRECT regarding blood group B?
- AIt shows two types of genotypes.
- Correct answerBAntibody 'a' is present on the surface of WBCs
- CAntigen B is present on the surface of RBCs.
- DThey can receive blood from B and O blood groups.
Solution
Blood group B is characterized by the presence of antigen B on the surface of red blood cells (RBCs) and antibody 'a' (anti-A) in the blood plasma. Antibodies are not present on the surface of white blood cells (WBCs).
The possible genotypes for blood group B are $I^B I^B$ and $I^B i$, meaning it exhibits two types of genotypes.
Individuals with blood group B can safely receive blood from donors with blood group B and blood group O.
Therefore, the statement that antibody 'a' is present on the surface of WBCs is incorrect.
Answer: Antibody 'a' is present on the surface of WBCs
The possible genotypes for blood group B are $I^B I^B$ and $I^B i$, meaning it exhibits two types of genotypes.
Individuals with blood group B can safely receive blood from donors with blood group B and blood group O.
Therefore, the statement that antibody 'a' is present on the surface of WBCs is incorrect.
Answer: Antibody 'a' is present on the surface of WBCs
Hence, the correct answer is option: 'B'.
