Can parents with blood type AB produce off spring with type O blood?

No. The B antigen is different from the A antigen, and type O blood has neither A nor B antigens. To get a child with type A blood, one of the parents has to donate the A antigen gene, which means one of the parents must be either A or AB.

∙ 10y agoWe are looking for the possible blood types of a baby.
Parental information:
- Mother type AB -- mom can give the baby Gene A or B
- Father type AB -- dad can give the baby Gene A or B
Baby receives one gene from each parent:
- Baby is type AA
- Baby is type AB
- Baby is type BB
Generally speaking, since there is no O gene from either parent to contribute to the baby, the offspring cannot be Type O.
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.
- Baby is type O
The baby has to have the inhibitory gene to mask the expression of his ABO gene.
If the inhibitor gene is "on", then the baby will be Type O no matter what blood type his genes code for.

∙ 11y agoNo they would either make AB, A, or B

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.
If you have o negative blood do your parents have o blood too?
They could, but they don't need to. Both of your parents must have at least one O allele, meaning neither can have type AB blood. They must be either BO, AO or OO to produce a child with type O blood.
Can 2 type o blood types have a blood type a child?
Parents of blood type O can only have children with blood type O. Because type O is recessive, you know that the parents are homozygous O.
Aaron has blood type O. Can either of his parent have blood type AB?
no, blood type AB has gennotype IA,IB while blood type o has the genotype II. Each of his parents passed on an allele,So neither could have blood type AB
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.
How can two parents with blood type O negative have a child with blood type AB?
They cannot. Two parents with type O negative blood will produce offspring of type O negative.
What is the only genotype that will produce O type of blood?
The gentotype is ii that will produce blood type O. The allele i is recessive, so both parents must have at least one i allele, and the child must be ii (double recessive) to be blood type O. The parents' blood types do not have to be type O- the genotypes Ai (blood type A, as A is dominant), and Bi (blood type B) can produce blood type O offspring, as long as the child inherits the i allele.
What two blood types from parents produce blood type A in child?
Parents must be blood type A or O. Any other blood type will not result in a sole A type child. It might result in several other combinations though, which are not relevant to this question.
Can parents with O blood and B- blood produce a child with A blood?
No - this is not possible. The child must have one parent with an A allele in order to have type A blood. Neither of these parents have an A allele - so this is not possible.
Can parents both have o positive blood type and have a child that has b positive blood type?
No. Generally when both parents are Type O+ they produce Type O+ or O- children. See also: http://www.bloodbook.com/inherited.html
What would a baby's blood type be if both parents have o negative blood type?
The baby will be type O negative. It cannot be any other blood type.
How many percent of human blood type b does produce a baby with a type b blood also?
The baby's blood group depends on the genotypes of both parents, not just one.
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 and a type blood produce an ab baby?
Can a-mother and o+ father have ab+ baby
What blood type can a baby have if both parents have type A blood?
If both parents have type A blood then the baby should have type A blood. or type O blood
Can parents both blood type B positives have a child with O positive blood type?
Yes, two B positives can produce an O positive child.
Could a female with B type and a man with AB type blood produce an offspring with O type blood?
Yes, an individual with blood type B can produce an offspring with blood type A. The explanation for this is that a mother with the blood type A can have a child with a father who has a blood type of A or AB and produce a child with type A blood.
