What Blood Type Will Children Have if One Parent Is AB and the Other Is B?

Update Date: 2024-06-17 Source: Network

Blood is an indispensable part of the human body. There are mainly four types of blood groups: A, B, AB, and O. Of course, there are also other blood types, such as Rh-negative blood, which is also known as panda blood. Blood types have their own characteristics and obvious genetic traits. For example, if a couple has AB and B blood types, their children may have A, B, or AB blood types.

1. What blood type will children born from parents with AB and B blood types have?

If both parents have AB and B blood types, respectively, their children may have A, B, or AB blood types. The specific blood type is determined by genetic probabilities and cannot be controlled artificially. The blood type of the baby can only be verified through blood tests in the future. In rare and extremely rare cases, there may be blood type mutations, and the specific mutation is a random probabilistic event that cannot be predicted. During pregnancy, pregnant women should pay attention to undergoing four-dimensional ultrasound and Down's syndrome screening to rule out the possibility of some congenital diseases in the baby. Other matters are uncontrollable.

2. The role of blood type testing

(1) For medical blood transfusion: Blood transfusion with incompatible blood types can cause transfusion reactions. Severe anemia caused by various reasons and various acute and chronic blood losses require blood transfusion therapy and resuscitation.

(2) Before surgery: To prepare blood in advance in case of excessive bleeding during surgery, it is necessary to check blood types and perform blood matching.

(3) Neonatal hemolytic disease: When the mother's and fetus's blood types are incompatible, it can cause hemolytic disease caused by blood type antigen immunity. The most common is ABO hemolysis caused by the ABO blood type system. When the mother has O-type blood and the fetus has A-type or B-type blood, neonatal hemolytic disease or miscarriage is most likely to occur.

(4) For organ transplantation: Incompatibility between the blood types of the organ donor and recipient can lead to and accelerate the rejection of the transplanted organ.
