If the parents are Type AB and Type O could they produce an Type AB child?

We are looking for the possible blood types of a baby.
Parental information:
- Mother type A --can be AA or AO = contributes A or O gene
- Father type O --can only be OO = contributes O gene
- Baby is type AO = Type A
- Baby is type OO = 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.
If the Type O parent has the inhibitory gene affecting his B or AB type,
then the Type AB baby is definitely possible.

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.
If the parents are both blood Type A could they produce a blood Type AB child?
We are looking for the possible blood types of a baby.Parental information:Mother type A -- can be AA or AO = contributes A or O geneFather type A -- can be AA or AO = contributes A or O geneBaby receives one gene from each parent: Baby is type AA = Type ABaby is type AO = Type ABaby is type OO = Type OSince neither parent can contribute the B gene, it is impossible for this pairing to produce an AB child.
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.
If both parents are blood type o is it possible for their child to have a blood type a positive?
No, two type O parents can only have type O children. See the table below from www.dna-bioscience.co.uk/did_you_know_abo.shtml If you look at the row for mother's blood type O where it intersects with the column for father's blood type O, you will see that the child's blood type must be O. For the child to be Rh+, only one of the parents has to be Rh+.
Could a mother with type A blood and a father with type B blood produce a child with type B blood?
Yes! You could produce a child with either A or B blood.
If both parents have A blood type can they have a child with o blood type?
Yes. Both parents could be heterozygous, that is AO, and pass on the O to their child.
Could a type B child with a type A have a type A father?
No. The child would receive type a antigens from both of their parents and no type b antigens.
Could a child with type B blood have parents that are both type A blood?
Only if it was adopted...the only options for that child's blood type would be A or O if the biological parents are both Type A.
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.
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.
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.
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 both parents have 0 positive blood types could child have type A?
No.
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.
How could two parents with blood types a and b have a child with o?
If the parents had the genotypes AO and BO, then they could have a child with Type O blood (there would be a 25% chance of this occurring).
Could a child from parents with type o blood and type ab have type o blood?
The parent with type O blood will produce gamets of IOIO and other parent with type ab blood will produce the gamets of IAIB so after mating the probability of progeny is IAIO:IBIO = 1:1 but no IOIO so in above case the probabitly of child with o blood group is zero or nill.
