Blood types, as people commonly know, has a classification which is simply based on two things:

* ABO group

* Rhesus factor Now, the ABO group, depends on two antigens; antigen A and antigen B. which lie on the surface of the RBC:

* A person having an A antigen on his RBC cells will show a blood type of A * A person having a B antigen on his RBC cells will show a blood type of B * A person having both A & B antigens on his RBC cells will show a blood type of AB * A person having neither of those antigens will show a blood type of O Second, the rhesus factor, which depends on a single antigen; antigen D, which also lies on the surface of the RBC:

* A person having a D antigen is called an Rh positive, e.g. A, B and D antigens' presence exhibit a blood type of AB+ (universal acceptor)

* A person without the D antigen is called an Rh negative, e.g. Neither A, nor B, nor D antigens' presence exhibit a blood type of O- (universal donor). Both factors combine to form the blood types as we know them today.

It means "What is your blood group" or "which group does your blood belong to?"

For example, you might have heard people say "My blood type is A" or "My blood group is A +ve [A positive]."

So, here, the "A" and "A +ve" indicate the blood type.

Thus when a person asks "What is your blood type?" you are supposed to tell him/her your blood group.

Additional Note: Blood Types are determined by a protein known as antigens which line the wall of your red blood corpuscle (RBCs). So, if you have antigen B, then your blood type is B or if you have no antigen, your blood type is O , if you have antigen A your blood type is A and if you have antigens A and B your blood type is AB.

Can a child with blood type O have a parent with AB blood type explain?

No. A and B are dominant blood types and O is recessive. A parent with blood type AB can only donate a dominant A or dominant B. A child with blood type O would need to come from parents with one of the following combinations: A-A, A-B, A-O, B-O, O-O


Can a person with blood type AB donate blood to a person with blood type A explain?

Each blood type has it's identifying proteins, and will reject blood with the wrong proteins. Type A blood is anti-B, type B blood is anti-A, type O blood has both, and type AB blood has neither. Imagine if someone with AB blood tried to donate to someone with A. AB blood has identifying proteins A and B. The type A blood would recognize the B proteins and kill the cells. The same thing would happen with B, which would recognize the A proteins and kill the cells. Type O blood would recognize and reject both the A and B proteins and reject them. However, if someone who is type AB gives to AB people, their blood does not destroy neither protein A nor B, so it would accept it.
