Just because the babys blood and the fathers blood is different, it doesnt mean that there is a possibility that he ain't the father. For example, my fathers blood is different from my sisters and including but he still my father. I hope that answered your question.
You are A dominant, but you have the O+ recessive gene.
To rephrase what the others have said-
if the mother is A plus, she would be AA or AO bloodtype. The father is something with an O as well, if the baby has an O. Father could be BO< AO< OO etc. (or he could have negative blood, and still have a positive blood child from this union)
What else can I help you with?
Can ab mother and o plus father have ab baby is he the father?
No. The Mother is IAIB and the father is ii. So, in gamete formation, the mother will produce IA and IB, while the father only produces i. When the gametes fuse, there will be two possible genotypes (and phenotypes) for the baby: IAi (A blood type) or IBi (B blood type). The Rh factor (+ or - ) has no relevance in this question, really. The REAL father can be either: IAIB, IAi, or IBi. The child MUST get an IA or IB allele from the father.
What would be the blood type of the child if the mother is B plus and the father is A plus?
ab+ a+ b+
Can type 0 plus mother and ab plus father have an O plus baby?
No. The child will be either group A or group B, but not group O. This is because the father can donate only a group A gene or a group B gene, so since group A and group B are dominant over group O, the child could not have group O blood.
Mother o plus father a- any problem for baby?
Nope. Generally there may be problems only if mother is negative and the father is positive. The antibodies to A/B blood types are too large to pass through the placenta and so cannot hurt the baby.
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.
