Could a man with an AB blood type be the father of an O child?

Could a man with an AB blood type be the father of an O child?

For example, a man who has type AB blood could not father a child with type O blood, because he would pass on either the A or the B allele to all of his offspring. Despite their usefulness in this regard, ABO blood groups cannot be used to confirm whether a man is indeed a child’s father.

What blood types make an AB baby?

One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.

How does a child get O blood type?

If the Mother’s blood type is B, and the father’s blood type is O, then their child must be either B or O. For instance, if both mother and alleged father have type A blood, then the child can only have A or O blood.

What happens if one parent is O positive and the other O negative?

Yes, Mom or Dad may be positive, but that recessive negative gene is still floating around in his or her DNA. If it becomes paired with another negative gene from a similar positive-negative parent, that child will be negative even though both parents are positive.

Can AB and O have a baby?

Can an AB father and an A mother have an O baby? Yes they can. An AB parent can indeed sometimes have an O child. But it is by no means common.

Can AB father and O mother have o child?

Can an O positive mom and an O Negative Dad have a baby?

Yes this is definitely possible. In this case, the most likely explanation is that dad is a carrier for being Rh- and mom is a carrier for blood type O. What happened was that dad and mom each passed both an O and an Rh negative to the baby.

Can 2 O positive parents have AB positive baby?

Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations.

What blood type Cannot have babies?

When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.

Can a parent have AB and O blood types?

One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.

Can a parent with a and another with AB produce a child with AB?

One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.

Can a child have a different blood group than its 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.

Is it possible to have an O blood type?

In fact it would be fair to say that it is exceedingly rare. The one exception is in certain Asian groups. Some of these folks have a rare version of the ABO blood type gene called cis-AB. People with this gene version have an AB blood type but can easily have an O child.
