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 blood type O and AB have a child?
An AB and O couple producing an AB child cannot be explained in terms of the usual inheritance patterns. One would not expect the cord blood result to be AB when the mother is type O, however, in very rare instances, such as the cis-AB blood type, it is possible.
What blood types should not have babies together?
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.
What blood type does AB and O make?

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.
How does a child get AB blood type?
How are ABO alleles inherited by our children? Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter.
What is the healthiest blood type?
Of the eight main blood types, people with type O have the lowest risk for heart disease.

What percentage of offspring is blood type AB?
The chance that your child’s genotype is AB is 75% * 50% = 37.5% .
What happens if one parent is O positive and the other O negative?
Children who inherit an A-O combination will be type A, but, remember, they could still pass that O gene off to their children. As a result, their child could wind up as type O if the other parent passes them an O-type gene, too. That last fact explains how O-positive parents can have O-negative kids.
Why is O negative so rare?
People with O negative blood often wonder how rare their blood is since it is always in demand by hospitals and blood centers. If you have 0 negative blood, you have something in common with about 7 percent of the US population. … Fewer than 50 people in the entire world population are known to have Rh-null blood.
What blood type Cannot be mixed?
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens.
What is the golden blood type?
