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.
ab+ a+ b+
The blood type for both parents must be OO since the O blood type is recessive. That means the child will definitely be O. The mother, since she has an Rh factor of + must be either ++ or +-. The father must be --. So, if the mother is ++, then the child will be O+. If the mother is +-, then there is a 50% chance that the child is O- and a 50% chance that they will be O+.
It could be possible, but only if both the parents are heterozygous.If the mother is AO and the father is BO - there is a 25% chance the child will be OO (O blood group).However, if either or both of the parents are homozygous (AA or BB) - then they cannot have an O child.
The child can have either Rh positive or Rh negative blood. More information is needed on the mother's genotype to know for sure. With the information currently given, the child has a 25% chance of being Rh negative.
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)
A
A+
No!
Yes.... because blood trait A is dominant on blood trait O... the child will then have blood group A
The father's blood type can be O, A, or B.
A positive with highest probability
Yes, it is possible for both mother and father to be RH positive and a child to be RH negative.

Yes, as long as the mother has B in her blood type (either B or AB), the father can have O.
Mother is a plus child 0 plus what could father be?
The child would have A plus blood type since A blood type is a dominant trait while O blood type is a recessive trait
