We are looking for the possible blood types of DAD.

Available information:

  • Mother type O pos = can only be OO and Rh (++) or (+-)
  • Baby type A pos = can only be AO and Rh (++) or (+-)
Baby recieves one gene from each parent:
  • Dad can be AA (++) = Type A pos
  • Dad can be AA (+-) = Type A pos
  • Dad can be AB (++) = Type AB pos
  • Dad can be AB (+-) = Type AB pos
Since Mom can only give an O then Dad has got to provide the A, so he will be either AA, AO or AB. Everyone is Rh pos, so as long as baby gets one (+) gene, he will be Rh pos.

Yes. The mother would have to be either B or AB.


What blood type would a child be with a AB neg mother and O positive father?

The child would most likely have either blood type A positive or B positive. A child inherits one blood type allele from each parent, so with an AB negative mother and an O positive father, the child could receive the A allele from the mother and the O allele from the father, resulting in blood type A positive. Alternatively, the child could receive the B allele from the mother and the O allele from the father, resulting in blood type B positive.


If the mother is A negative and the father is B positive what type of blood can the baby get?

It would all depend on the Dominant and Recessive blood type genes in the mother and father it is near improbable to tell unless you take a blood sample to test the blood type. == A rhesus negative mother and positive father can produce either a rhesus negative or positive child. A type A and type O parental combination will only produce either type A or type O children. So an A- mother and O+ father will normally produce offspring having the possible blood groups of A+ or A- or O+ or O-. See the link for a full explanation.
