We are looking for the possible blood types of a PARENT.
Available information:
- Mother type AB --can only be AB = contributes A or B gene
- Baby type O -- can only be OO = has to receive an O from each parent
- Mom type AB + Dad type AA/AO = Baby type AA, AB, AO, BO
- Mom type AB + Dad type BB/BO = Baby type BB, AB, BO, AO
- Mom type AB + Dad type AB = Baby AA, AB, BB
- Mom type AB + Dad type OO = Baby AO, BO
HOWEVER: There is more to ABO blood typing that just the ABO gene.
There is also an inhibitory gene that will change any genotype into the phenotype O.
Therefore a person with genetically AB blood can be tested as having Type O.
If the baby's inhibitory gene has been turned "on", then no matter what ABO genes he receives from his parents, he will test out as a Type O.
What else can I help you with?
Can a child with type o blood have parents with ab blood?
"No, if each parent has AB then the child can be A, B or AB but not O." Not exactly. Yes, it IS possible for a child with Blood type O to have a parent with the AB Blood type although it is extremely rare. There are different reasons for this. One is the Bombay blood group. There is also Chimera, or 'vanishing twin'. 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. I am an O blood type child of an AB blood type parent, although we are not of Asian/European descent. I also have other siblings who are Blood type O so I know it is possible.
Can a daughter be blood type O when her father is blood type AB and her mother is A?
No, a child cannot have blood type O if one parent is blood type AB and the other parent is blood type A. Blood type O is inherited when both parents contribute an O allele, which is not present in this case.
Could a father with blood type o be the father of a child with blood type ab?
No, a father with blood type O cannot be the biological father of a child with blood type AB. Blood type O can only contribute an O allele to the child, not an A or B allele required for blood type AB.
A child is born with type ab blood. which of these statements is true?
The child must have inherited at least one A allele and one B allele from their parents. The child could have inherited an A allele from one parent and a B allele from the other parent, or may have inherited an AB genotype from one parent.
Mrs Smith has blood Type A her father has blood Type A and her mother has blood Type B. If Mr Smith has blood Type AB what is the probability that they will have a child with blood Type AB?
We are looking for the possible blood types of a baby.Parental information:Mrs Smith = Type AO = contributes A or O geneHer father Type A (AA/AO), Mother Type B (BB/BO)Mr. Smith = Type AB = contributes A or B geneBaby Type AB(?)Baby Smith receives one gene from each parent: Baby type AA,Baby type ABBaby type AOBaby type BOThe baby has a 25% chance of having Type AB blood.
How can a child that is born with type AB blood?
the child takes the A gene from one parent and B from the other. And the both of parent are supposed to be AB blood type, or one A blood type and the other B.
Could a parent with AB-blood type have a child with O-blood type?
No.
If you are AB plus can your child have the same blood type as you?
The child can have the same blood type. It is possible if the child obtains the allele IA from one parent and IB from the other. So if a person with blood type AB provides IA or IB and the other parent provides the other allele, then the child may have the same blood type i.e. AB positive.
Can b positive parent have child with a positive blood?
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
Can a child with blood type O have a parent with AB blood type explain?
No. A and B are dominant blood types and O is recessive. A parent with blood type AB can only donate a dominant A or dominant B. A child with blood type O would need to come from parents with one of the following combinations: A-A, A-B, A-O, B-O, O-O
Can parents with AB blood type have a child with O blood type?
"No, if each parent has AB then the child can be A, B or AB but not O." Not exactly. Yes, it IS possible for a child with Blood type O to have a parent with the AB Blood type although it is extremely rare. There are different reasons for this. One is the Bombay blood group. There is also Chimera, or 'vanishing twin'. 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. I am an O blood type child of an AB blood type parent, although we are not of Asian/European descent. I also have other siblings who are Blood type O so I know it is possible.
Can a child with type o blood have parents with ab blood?

If one parent has AB-blood type and the other has O-blood type what blood group will their child have?
Either A or B; AB and O are impossible.
Can parents both blood type b positive have a child with a blood type?
No. B type can only have B, O, and AB. A child with A blood would have to have at least one parent be A or AB.
Can you be the father if the baby don't have mine nor the mother blood type?
Yes. A mother with blood type A (AO) and a father with blood type B (BO) can have a child with blood type O (OO), one O from each parent. An AB parent and a A (AO) parent can have an B child (BO), an AB and a B (BO) can have an A (AO). An AB parent can never have an O child because it requires two recessive genes and an AB parent cannot donate a recessive O.
Can an O positive blood type parent produce an AB negative blood type child?
yes
Can an A negative parent and a A positive parent have a child who is AB negative blood type?
it can be rare only
