Question

What makes the blood type of people different?​

Answer 1

Answer:

Whether your blood type is A, B, AB or O depends on whether you have, or don't have, certain antigens (named A and B) on your red cells. The presence or absence of A or B antigens gives us four main blood types: A type blood has only A antigens on red blood cells. B type blood has only B antigens on red blood cells.
