Can the parents with the blood type A and B have a child with O blood type?

No. They can not . Blood group antigens are expressed co dominantly that is if a person has both A antigen and B antigen he will express both. There is no way B will suppress expression A antigen. For a person to have AB blood group one of his parents should have either A or AB and the other should have either B or AB. How ever there is a remote chance of having a mutation which can express both antigens. How ever it is a very very rare situation.

Each person receives one blood group allele (you may think of this as a code) from their mother, and one from their father, and there are three different alleles for ABO blood grouping, namely A, B and O.
While A and B are co-dominant, meaning neither one will 'defeat' each other in the actual expression of the gene, the O allele is a recessive one, meaning it will not be expressed when there is an A or B allele.
For Blood Type A, possible combinations of alleles include AA, and AO.
For Blood Type B, possible combinations include BB, and BO.
For Blood Type AB, it means that the A allele and B allele are expressed together, ie. the genotype is AB.
For type O, the only possible genotype (code) for this is OO, since the blood group O will not be expressed with the presence of a single A or B allele.
Hence two parents will Blood Type O will both have only alleles for O blood group to pass on to their offspring, and naturally their offspring will be of a Blood Type O.
Of course, if there are genetic mutations that's another story..

∙ 10y agoWe are looking for the possible blood types of a baby.
Parental information:
- Mother type B --can be BB or BO = contributes B or O gene
- Father type B -- can be BB or BO = contributes B or O gene
- Baby is type BB = Type B
- Baby is type BO = Type B
- Baby is type OO = Type O

∙ 12y agotype of blood group AA AO BB BO AB OO
Father Blood Group B either BB or BO
Mother Blood Group B either BB or BO
So the child can be either type B or O
if it is AB, then go for a DNA testing.....................

∙ 16y agoYes. The blood type of the parents has nothing to do with their sexual/reproductive compatibility. It only plays a part in determining the blood type of the child.
Wiki User
∙ 15y agoNo. In the given scenario, only blood type A and O (considering that both parents are heterozygous) is possible.

∙ 13y agowell, with genes and blood type... it can't be true, because A+B=AB. but I'm just human.. I just can calculate and estimate it. only God knows the really truth ;)

Can parents with a positive blood have b positive child?
If they both have type A blood, they cannot have a child type B.
Is it possible for a baby to have a different blood type then the parents?
It is possible if your parents have different blood types. Example, if your father is A with a recessive O, and mother is B with a recessive O, you could easily land up with a O blood group. However, an AB father can have only an A, B or AB child depending on the mothers blood group, but surely NOT 'O.'
What type blood do parents have to have for their child to have ab positive blood?
A & B + respectively
Can O positive blood group and B positive blood group parents have child?
Yes, blood type has no bearing on weather or not the parents can have a child
Can parents with blood type a and b hae a child with o blood type?
No, Parents of a type b child would have to be either AB, BB, BO or OO.
What blood type must the parents of a B child be?
The parents must have both blood type B or blood type 0 and B.
Can parents with a positive blood have b positive child?
If they both have type A blood, they cannot have a child type B.
How is a child's blood type determined?
The child's blood type is determined by his or her parents' blood types. If both parents have type A, the child can have either type A or O. If both parents have type B, the child can have either type B or O. If one parent has type A and the other parent has type B, the child can have type A, B, AB, or O, but he/she is most likely to have type AB. If both parents have type O, the child will have type O.
Is it possible for 2 parents with type b blood to have a child with Type 0 blood?
Yes, they can have a child with blood type AB, which is the rarest of the four types.
Can parents with O blood have b positive baby?
No, if both parents have O type blood they cannot have a child with B type blood. At least one parent would need to have type B or AB blood in order for the child to inherit a B allele.
Is there a posibility to have a child that is blood type -A A couple who are blood type B and blood type O?
No. It is not possible for a child to have A if the parents are O blood type. If both parents have type O blood, then their children will also have type O blood. However, two parents with type A or type B blood (both the same or one of each) can sometimes have a child with type O blood. That is because the gene for type O blood is recessive. But they must carry the O type. However, two parents with type AB blood can have a child with type A, type B, or type AB blood, but cannot have a child with type O blood.
Can parents with o blood type to have a child with b blood type?
If both parents are type O blood they will only have type O children
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.
How can a baby have b negative blood when both parents are b positive?
If both parents have Type B blood the only blood type the child can have is either B or O not looking at whether one of the parents is negative or not.
Is it possible for a baby to have a different blood type then the parents?
It is possible if your parents have different blood types. Example, if your father is A with a recessive O, and mother is B with a recessive O, you could easily land up with a O blood group. However, an AB father can have only an A, B or AB child depending on the mothers blood group, but surely NOT 'O.'
If a woman with O blood has a child with a man with B blood could the child be A blood?
No, the child has to have one of the parents blood type.
Can parents both blood type O have a child with b blood typo?
No
