It's impossible because A blood type could be AA or AO and AB is only AB so the children could be AA, AB,AO (which is Atype), or BO (B type) BUT NEVER OO (o type). For the child to be O type they should get one O from one parent and the other O from the other parent. In the case mentioned AB can give A or B NOT and NEVER O. This question is answered by an MD

∙ 13y agoNo. The "O" in blood typing should actually be viewed as a zero, meaning the absence of either A or B markers in the blood. So, a type O person has no A nor B markers in his or her blood. Because such a person has no A or B trait to pass on to a child, such a parent could not possibly have passed on a B trait to the child. And the parent with A positive blood has no B trait to pass on, either. Therefore the child from such a pairing cannot be AB positive, because neither parent has the B trait to pass on to the child.

Parent 1 is O positive. This means both the blood-type genes are turned off and at least one of the Rh factor genes is turned on. Maybe both.
Parent 2 is AB negative. This means one of the blood-type genes is set to A and the other to B, and both Rh factor genes are turned off.
Because both the A and B blood type genes are dominant, you only need one of them to cause the child to be either A or B. This means any child these two have will be either A or B, but never O and never AB.
The Rh factor is a little trickier, but not too much. If one of Parent 1's Rh factor genes is on and the other off, the child can be either Rh positive or Rh negative. If both of Parent 1's genes are turned on, the child will always be Rh positive.

∙ 12y agoYes, absolutely. The O+ parent can only give a type O gene, because it is recessive and the genotype of this parent is OO. The type AB parent has a 50-50 chance of passing on either a type A gene or a type B gene to their offspring, so in this pairing, you'd expect half of the children to be type A and half to be type B. The positive rh factor is dominant, so if both parents are rh+, the children most likely will be also, although it is possible to have rh- children if both parents carry this recessive gene.

∙ 13y agoNo. An AB parent can only produce an A, B, or AB child.

∙ 9y agoits impossible for a O parent to have an ab child.

∙ 13y agoNo, the child could only be B+ or O+.

What blood type would a child be with a AB neg mother and O positive father?
The child could be A+, AB+, B+, A-, AB-, or B-. That is, any blood type except O positive or O negative.
Can parents who are B negative and O positive have a AB positive child?
No
Can parents both blood type b positive have a child with blood type ab positive?
possibility of b or o not ab
Can parents with B negative and AB positive have a child with O negative?
No.
What are the possible blood types of a father being that the mother is b positive and the child is ab positive?
You dad can either be O, AB, A,or B and he can be positive or negative.
Can an o negative and a ab positive had an o positive child?
If a person who is O- were to mate with a person who is AB+, they could not have an O+ child. They could have a child who is A-, A+, B-, or B+, but not O.
Can O positive and B positive have an ab positive child?
No, an O-group parent cannot have an AB-group child at all.
If both parents are O positive can they have a child that is A positive?
No. If both parents are type O, the child will be O. If both are A, the child can be either A or O. If both are B, the child can be either B or O. If both are AB, the child can be A, B, or AB (but not O).
What blood type would a child be with a AB neg mother and O positive father?
The child could be A+, AB+, B+, A-, AB-, or B-. That is, any blood type except O positive or O negative.
Can parents who are B negative and O positive have a AB positive child?
No
Can a o positive and a b positive have a ab negative?
No, an O-group parent cannot have an AB-group child at all.
Can an o positive and a b positive produce an ab blood child?
yes
Can a AB poitive mother and a B negative father have O positive kid?
An AB+ and B- couple can't have a child with blood type O. They can have children with blood types A, B, or AB, and can have children with Rh negative or Rh positive blood.
Can parents both blood type b positive have a child with blood type ab positive?
possibility of b or o not ab
Can an A positive father and a B positive mother have a B negative child?
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
Can a child be B positive if mother is O negative and father A positive?
No, the father would have to have B or AB.
Can parents with B negative and AB positive have a child with O negative?
No.
