Does the blood group of parents affect baby?

Yes, the blood group of parents can affect the blood group of their baby. This is because blood group is determined by the presence or absence of certain antigens on the surface of red blood cells. These antigens are inherited from both parents, and the combination of antigens that a baby inherits determines their blood group.

There are four main blood groups: A, B, AB, and O. People with blood group A have only A antigens on their red blood cells, people with blood group B have only B antigens, people with blood group AB have both A and B antigens, and people with blood group O have neither A nor B antigens.

When a couple with different blood groups has a baby, the baby can inherit any combination of antigens from their parents. This can result in the baby having the same blood group as one parent, the same blood group as the other parent, or a different blood group altogether.

For example, if a couple with blood groups A and B has a baby, the baby could inherit A antigens from the A parent and B antigens from the B parent, resulting in the baby having blood group AB. Alternatively, the baby could inherit A antigens from the A parent and O antigens from the B parent, resulting in the baby having blood group A. Finally, the baby could inherit B antigens from the B parent and O antigens from the A parent, resulting in the baby having blood group B.

In addition to the four main blood groups, there are also a number of other rare blood groups. These rare blood groups are often inherited from both parents, and can cause serious health problems if not properly managed.

If you are planning to have a baby, it is important to talk to your doctor about your blood group and how it could affect your baby. This will help to ensure that your baby receives the proper care and treatment.
