I'm not certain what this question is really asking. If read literally, I would assume yes, a mother and a father can parent an AB positive child provided they are capable adults. If the question is asking can a man have a child that has a different blood type than his, the answer is yes. A baby will have either mom or dad's blood type. Now if dad is O pos and mom is AB pos and the baby's blood type is neither one of those, I would suggest DNA testing for that baby.
What else can I help you with?
What is the blood type of the father if the mother is O plus and the child is A?
Must be AA, or AO because the mother having O blood, which is homozygous recessive, must be OO. The signs mean little here except the father must carry them and the child inherited them from the father.
Can b positive child have an a negative father?
Yes, it is possible for a child to have a different blood type than their father. A child inherits one blood type allele from each parent, so if the child receives a B allele from their mother and an A allele from their father, they can have blood type B.
Can an O positive mother and an O negative father have an A positive child?
No. The child will be type O+ or O-.
Can an B positive blood type mother and an B positive blood type father parent an A positive child?
No. The child will be type B or O, it cannot be type A.
If a mother has O negative blood and her child has A positive blood what type of blood should the father have?
The blood would be A+, the child's is always pretty much what the Father's is.
Should a child with A positive be same as the mother?
Blood types are received from the mother and father, so the child can be the same type as the mother if the father's type allows it.
Can a Type B child with a Type A mother have a father with Type A blood?
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
Can a type A mother and type A father have a type B child?
No that's impossible.
Is it possible to have a child which is type A when the father is type b and the mother is type O?
No
If mother and father is A blood group can child be B positive?
If the mother is A, and the father is A, then the child will only have A antigens and will thus be blood type A. If father or mother are AB, then the child can end up with AB, A, or B blood type. http://en.wikipedia.org/wiki/Blood_type
Could a father with a blood group ab have a child that is O blood group?
Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
