antigen a and b and they have no antibodies.
Nothing is wrong because blood AB has antigen A and B.
Blood type has to do with the antigens found on the surface of your red blood cells. Type A has the A antigen, type B has the B antigen, type AB has both, and type O has neither.
Type AB blood doed not contain any antibodies. I does have Antigens A and B.
blood type A have antigen A and anti body B blood type B have antigen B and anti body A blood type AB have antigens A and B and do not have anti body blood type O do not have antigen but have anti bodies A and B
blood groop o has no antigen
Why not? If a mother is type AB, it means she has A and B antigens in her and zero antibodies. If the father is type A, B, or AB, there is a chance that the child can be type AB. It all depends on luck. If the father is type A, and he happens to donate that antigen, and the mother happens to donate the B antigen in her body, then voila! Type AB. If the father is type B, and he happens to donate that antigen, and the mother happens to donate the A antigen in her body, then voila! Type AB. If the father is type AB, and he donates either. The child can be type AB as long as the mother donates the opposite one. It's really all chance. If you are asking whether the mother will reject the blood type in the child, then of course not. They are the same blood type. Perfectly compatible.
Rh is an antigen. If you have the antigen, your blood type is A+, B+, AB+, or O+. If you don't have the antigen, your blood type is A-, B-, AB-, or O-. People WITH the Rh antigen, can receive from/give to people with Rh+ or Rh-. People WITHOUT the Rh antigen, can ONLY receive from/give to people with Rh- blood. (meaning people without the antigen) If Rh- and Rh+ blood comes in contact, the Rh- will produce antibodies towards Rh+, and at the second contact with the blood, will cause agglutination.
Because the immune system of anyone with type AB blood is used to the presence of both the A and the B antigen on red blood cells. Therefore it will not fight type A blood with the A antigen present. (The immune system never detects the lack of antigens, only their presence). On the other hand, a person with type A blood carries only the A antigen on the surface of their erythrocytes. Their immune system detects and fights the B antigen.
1-Type A ... which has antibodies : B ... and Antigene : A2-Type B ... which has antibodies : A ... and Antigen : B3-Type AB . which has No antibodies ... and has Antigen : A and B4-Type O .. which has antibodies : A and B ... and has No Antigensfrom this information's, you can notice that AB blood type doesn't have Antibodies that's why it accept all types during blood transfusion, when there is no antibodies this means that the body will not consider the other blood types as foreigners.
The mother can be type A or AB. She cannot be type O or B.
it is the best blood type because this person accept all types (A,B,AB,O) with out any problem, but the Ab person cant only give blood to the AB category. that's why it is a universal acceptor for him/her and limited doner for only the AB persons.
Previous answer: 0 blood type has no antigens.My improved answer: the Bombay phenotype has no antigens.O blood group has H antigens (but does not have A or B antigens), whereas in the Bombay phenotype blood group, even the H antigens are absent.Glenn LowNUS Life Sciences Studentsimmune system
