We are looking for the possible blood types of a PARENT.
Available information:
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.
no, its impossible ,because blood type AB contains antigen A and antigen B on the surface of red blood cells because genetically there are allele A and allele B in the gene so when the assortment of allels occure in meiosis there must be either allele A or B ,but in order to have O blood type there must be no alleles in the gene location.
No. O is recessive and must be homozygous to be expressed. If both parents were O, then this would be the only possible cross.
OO X OO
------------
Not disagreeing with, but adding on to the above: Unless something very unusual is going on, two type O parents would not produce type AB offspring. Having blood type O means that you carry neither the gene for type A nor the gene for type B; having blood type AB means you have both those genes -- so two type O parents would normally have a type O child, and a type AB child could come from one type AB parent and one parent of any blood type, or from one type A parent and one type B parent.
Unusual things that could happen to produce unexpected genetic blood-type results include a functional mutation that turns an un-expressed or faulty copy of the A or B gene in a parent into an expressed copy in the child, or chimerism or mosaicism, where some cells in a body (including, in our hypothetical, most of the blood-producing cells in one of the parents) are genetically different from other cells in that same individual (including, in our hypothetical, the gonads of that parent). These things are far less likely than an error either in the blood tests or in the attribution of parentage, but they do happen.
No, genes come in pairs, or at least for blood types, which means if your A you are really AA or AO, O is a recessive gene and is ignored unless it is OO, which is just O, so even if one of your parents is AO and the other AB, it is impossible to get the combination of OO.
yes it is possible that a child can get o blood from a parent with ab. =)=)=)=)=)
No - the child needs to inherit at least one of the parent's alleles. Therefore if the parent has blood type AB, they must donate either an A or a B to the child.
Babies inherit mostly in all but rare cases, only one of the blood type alleles A, B, or O from each mom and dad. So, even if each parent had type AB, the kid could have AA, AB, or BB blood.

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.

"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.
If the parent's blood type is AB and B, the possible blood type of the baby is A, B, or AB.
If a parent's baby is having AB and O blood type, respectively, the baby's possible blood type will be A or B.
No. Neither parent can be AB blood type. Each parent must have at least one resessive gene for O blood type. Either parent could be type A or B or O.

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.
The baby could have almost any bloodtype except for O.
If one parent is B+ and the other parent is AB +, the child could be any blood type except type O. If the genotype of the parent with phenotype B is known, more detail could be given.

Here we have a parent who is OO, and therefore can only contribute an O gene.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 Type A, B or AB blood, then the Type AB baby is definitely possible.
The blood type A is determined by having either two A alleles (genotype AA) or one A and one O allele (genotype AO). In this case, since the parents have blood types AB and A, they can only pass on an A allele or a B allele to their child. If the parents have a daughter with blood type A, it means they both contributed an A allele, as the daughter cannot have a B allele since her blood type is A. So, the genotype of the daughter is AO. Now, if we consider Baby Y, we can infer that Baby Y could inherit one A allele from one parent (let's say from the parent with blood type A) and one A allele or one B allele from the other parent (the parent with blood type AB). Therefore, Baby Y's genotype could be either AA or AB.
