More than just two blood types are not compatible with each other. The four basic types of blood are: A, B, AB, O(not counting Rh).Type A blood can only receive blood from type A and type O. However, type A blood can donate their blood to type A and type AB. Because if a person needs a blood transfer, it MUST be from a donor with a compatible blood type. Otherwise, the transfer will kill the recipient. More elaborately, bl â¦ ood types are determined by the presence of two types of compounds in the blood.
