Can a parent with ab blood type have a child with ab blood type?
Wiki User
∙ 6y ago
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.

∙ 15y agoDepends on what the mother's blood type is, but they could be A, B, or AB.
They can't be o because A and B are both dominant.

depending on which genes get transmitted.

b- 25%
AB- 50%

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.
A child is born with type ab blood. which of these statements is true?
A+ Neither parent can have type O blood
What does dominant means?
Co-dominance happens when two genotypes are expressed at the same time. For example, one parent can have blood type A and one parent can have blood type B and together produce a child with blood type AB. If two parents have the blood type AB, the child has a chance of being mentally ill.
What blood types can be formed by crossing A genes with B genes?
If the parent's blood type is A and B, respectively, the possible blood type of their child are A, AB, B and O.
Can a woman with type ab blood have a child with type o?
NO. Not at all. Each parent has an A or a B to contribute to the child. Therefore, the only possibilities for the child are: An A from each parent (making it an A) A B from each parent (making it a B) and An A from one, and a B from the other, (making it an AB). This a super-simple answer. For more detail on ABO blood grouping, type in ABO on wiki. NO. Not at all. Each parent has an A or a B to contribute to the child.

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.
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 parents with AB blood type have a child with O blood type?

I also have other siblings who are Blood type O so I know it is possible.
Do your children have to have same blood as you?
No - children do not have to have the same blood type as the parents. For example, if one parent has blood type A and the other has blood type AB, the child might have A, B or AB blood types. (For the child to have B, the parent with blood type A would need to be heterozygous, Ao)
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.
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 an O positive blood type parent produce an AB negative blood type child?
yes
A child is born with type ab blood. which of these statements is true?
A+ Neither parent can have type O blood
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.
