For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type. Only people with at least one Rh-negative factors will have a negative blood type, which is why the occurrence of Rh-negative blood is less common than Rh-positive blood.

Do babies always have the father's blood type?

No it doesn't. Neither of your parents has to have the same blood type as you. For example if one of your parents was AB+ and the other was O+, they could only have A and B kids. In other words, most likely none of their kids would share either parent's blood type.

Type O-positive blood can be transfused to any positive blood type: A-positive, B-positive, AB-positive, and of course other O-positives.

What happens if blood type doesn't match?

The same type of response can occur during a blood transfusion if your donor's blood type doesn't match with yours. In that case, your blood cells could clump and cause potentially fatal complications,” explained Douglas Guggenheim, MD, physician at the Abramson Cancer Center Cherry Hill.

Does the father's blood type matter in pregnancy?

You inherit your blood type from your parents. If an Rh-positive baby's blood passes to its Rh-negative mother during pregnancy (or delivery), the mother's body will attack the baby's red blood cells.

Identical twins will always have the same blood type because they were created from the same fertilized egg (fraternal twins can have different blood types — again, providing the parents do — because they are created by two fertilized eggs).

Do all siblings have the same blood type?

Brothers and sisters don't always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.
