A person with A positive blood may be a carrier for O negative blood. If the other parent is also a carrier of those traits, the baby could be O negative.

∙ 13y agoThe actual blood type of a child is determined by the dominant blood type between the two parents. A and B are both dominant over O, which means a child that receives an A blood type from the father and an O blood type from the mother will have an A blood type.
Subsequently, A and B are considered to be codominant, which means a child inheriting an A blood type from the mother and a B blood type from the father will most likely have an AB blood type. Only two recessive O blood type genes from both parents will result in a child having an O blood type.

What blood type do the parents have to be to make an A positive baby?
One of the parents must be A or AB, and one must be positive.
Can a baby with ab positive blood group come from parents with o positive blood group?
Yes! Yes indeed. Does the baby look like the mailman? No. O parents can't make AB babies.
Can negative and a positive blood type make a positive?
If one of the parents is A positive, the child could be A positive.
Can a male having oo positive blood mother A positive blood make baby B positive Blood?
Theoretically no, the child could only have A or o blood.
Is rh negative blood compatible with o positive?
can two o positive blood types make an RH Negitive baby
Can A- blood and A plus blood make O- blood?
It is possible for the baby to be O if both parents were Ao
Can O positive and an A positive make O negative baby?
A person with A positive blood may be a carrier for O negative blood. If the other parent is also a carrier of those traits, the baby could be O negative.
Can a mother with B positive blood type and a father with 0 negative blood type have a baby?
Yes, anyone can make a baby. It doesn't matter what blood type you have.
Can two parents with b positive make o positive?
Yes. The child will be either A positive or B positive or even AB positive. If the grandparents have a negative (A negative, B negative), there is a slight chance that the child will have a negative. A type O is out of the question. The fact that there are two positive parents means that there is no risk to the mother of Rh negative disorders.
Can two o positives make an o negative?
Yes this is true only if both parents are heterozygous positive. This means that the parents genotypes are +- for blood type. + blood type is dominant over - blood type, so this means that one can only have negative blood type if their parents are either heterozygous or homozygous recessive. A helpful tool to finding out the probability for this question would be to use a punnett square. If you used this method you would find out that two heterozygous positive blood type parents have a 25% chance of producing offspring with negative blood type.
Can siblings have a positive and b positive blood type?
Yes, if one parent had an AO genotype and the other had an OO genotype.
Can two parents with A negative blood type make a O negative baby?
Yes
