ABO blood type There are four main blood types, namely A, B, O and AB. According to statistics, type A accounts for 27.51%, type B accounts for 32.33%, type O accounts for 36.49%, and type AB only accounts for 9.67%.
In medicine and genetics, the blood type of the parents is often used to infer the blood type of the child. If both parents are type O, the child must have type O blood and no other blood type is possible. . Another example is if one parent is type O and the other parent is type B, their children can be type B or type O. But sometimes it is difficult to determine. For example, if one parent is type A and the other is type B, the child can have any of the four blood types. The ABO blood type system is familiar to people and is an extremely important blood type in blood transfusion work. Ignoring the identification of the ABO blood type or making errors in the identification method will cause hemolytic transfusion reactions, which can lead to death in severe cases.
