Can siblings have different 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.

Can a child have a different blood type than either parent?

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.

Why is Rh-negative blood so rare?

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.

Which parent determines the blood type?

“There is a misconception that blood type comes from one parent more than the other,” says Suzanne Seitz, genetic counselor at Fairfax Cryobank. “Both the egg source and the sperm source determine the blood type.”

Can O+ and O+ have a baby?

Is O+ a rare blood type?

38% of the population has O positive blood, making it the most common blood type. O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).
