Can your blood type not match your parents?

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.

Can a baby have a different blood type than the parents?

Yes, a child is able to have a different blood type than both parents. Which parent decides the blood type of the child? The child’s blood type is decided by both parents’ blood type. Parents all pass along one of their 2 alleles to make up their child’s blood type.

What determines baby blood type?

Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

Can a child have different blood type than their parents?

1. Can a child have different blood type than both parents? Yes, the child can have a blood type different from its parents. For instance, parents with blood types AB and O can give their children either A or B blood types, which are different from the parents’ blood groups.

What is a child’s blood type if the mother has AO?

So the child’s blood type depends on the alleles that the parents carry. For instance, if the mother has the blood type AO and father has blood type BO, the child can end up with any one of the blood groups: A (25\%), B (25\%), AB (25\%) or O (50\%).

What is the difference between the alleles A and B?

The alleles A and B are considered codominant while O is considered to be the silent allele. Each parent gives one of their two ABO alleles to the child (3). Mother with AB blood type can either pass the A or B allele to the baby. Likewise, a father with O blood type can only pass O allele to the baby.

What is the dominant allele for blood type 0?

Alleles A and B are dominant, and the allele 0 is recessive. It means that only people with 00 alleles can have the blood type 0. Our calculator takes into consideration an additional classification that divides blood into two groups: Rh+ and Rh-. They also describe the presence or absence of a particular antigen – in this case, the Rh (D) antigen.
