Can a child have a blood group different from his her 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.

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

A baby may have the blood type and Rh factor of either parent, or a combination of both parents. The Rh positive gene is dominant (stronger) and even when paired with an Rh negative gene, the positive gene takes over.

Can two O positive parents make an O negative child?

A. Before I delve into the science, let me quickly stop any tongues that might be wagging if you are asking about a paternity debate: Yes, two O-positive parents could have any number of O-negative children. In fact, according to the experts, most children who are O-negative have parents who are O-positive.

CAN A and B blood make O?

Someone who has an A and a B version of the blood type gene makes both A and B proteins. And so is AB blood type. They are B blood type but can pass the O onto their kids. So two B parents can make an O child if both parents are BO.

Can a mother and father with different blood types have a baby?

So, for example, a mother who is type O and a father who is type A could have a child who is type A. 4  The reason the baby wouldn’t have type O blood, like his mom, is because the gene for O is recessive. Not all non-matching combinations of blood types are problematic.

How do you determine the blood type of a child?

The charts below can assist you to determine either: 1. The ABO blood type of the child when the blood type of the father and the mother are known (top chart), or. 2. The ABO blood type of the father if the blood type of the child and the mother are known (bottom chart).

Can the blood type of the father predict paternity?

On the other hand, if the mother’s blood type is A, and the father’s is B, the child could be ANY of the four blood types A, B, AB or O so its ability to predict paternity is minimal in this case. When both father and mother contribute an A gene, their child has Type A blood.

What is the ABO blood type of the father?

The ABO blood type of the father if the blood type of the child and the mother are known (bottom chart). ABO blood types can be complicated to understand. This is mostly due to the fact that the ‘O-type’ antigen is masked by the presence of an A- or B-type antigen.
