If they're homozygous (AA, BB): AB is possible.
If they're heterozygous (Ai, Bi): A, B, AB, or O is possible.
If A is homozygous but the other not (AA, Bi): AB or A is possible.
If B is homozygous but the other not (BB, Ai): AB or B is possible.
They attack each other and clot. The types (A,B, AB, O) are named for their antigens
the blood cells in the a blood attack the b blood cells
Yes, you can have a sister with blood type O and you can be blood type B. This can happen if you have one parent with type AB or B blood, and other parent with type O or B blood.
The short answer is that the Type B patient has antigens for that specific blood type, so when type A is mixed with the type B, the antibodies in the B blood kill the A blood cells, making it useless.
They will be fine because I know someone who has tried it.
Nothing is wrong because blood AB has antigen A and B.
No, type B blood does not have A antigens. Type B blood has B antigens.
what happens when blood type AB is mixed with blood type A or B?
If a parent's baby is having AB and O blood type, respectively, the baby's possible blood type will be A or B.
blood type A has type A antigens. blood type B has type B antigens.
the blood will coagulate as the body identifies the A+ blood as foreign
No - blood type B cannot donate to blood type O. This is because blood type B contains B antigens, and blood type O contains Anti-B antibodies. However, blood type O can donate to blood type B.
blood type B
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.
