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.

I was told that a mother that is a+ and child is 0+ that it OK for the father to be 0-
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+.
The father's blood type would have to be A. This is because O is a recessive blood type and needs two O's to produce a child with and O blood type. So if the daughter is an A blood type so must her biological father's.
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.
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.

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