That is always possible if both the parents are heterozygous for Rh antigen gene. It means that both the parents. There are 2 different alleles for the Rh factor known as Rh+ and Rh-.Someone who is "Rh positive" or "Rh+" has at least one Rh+ allele, but could have two. Their genotype could be either Rh+/Rh+ or Rh+/Rh-. Someone who Rh- has a genotype of Rh-/Rh-. If their genotypes are Rh+/Rh-, then their is possibility of of Rh- also.

Type O blood is also recessive to type A, so both parents could be heterozygous type A's. Their genotypes would have to be A/O.

Can a father with A-negative blood have a child with A-positive blood?
Yes, a father with A negative blood can have a child with A positive blood. If he does, the mother must have a positive Rh factor, and the mother's blood type may be any of the possibilities.
Is it possible for a child to have O negative blood if the mother has A positive blood and the father has A positive blood?
No.
Can a child have o positive blood if the mother has A positive and the father has A negative blood?
yes.
If the mother has B positive blood and the father has O negative what would the child's blood type be?
B positive or negative or, O positive or negative.
Can a mother with B positive blood and father with O positive blood have a baby with B positive blood?
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
Can a mother with a negative blood and a father with ab negative blood have a child with b positive blood?
yes
If a Mother is A positive blood group and a Father is A positive blood can they have a child that is A negative blood group?
95% not.
Can a mother with A positive blood and father with O positive blood have a baby with A negative blood?
No. Rh negative is a recessive gene. Positive people do not carry it.
Can a o negative blood type father and a negative blood type mother have o positive child?
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
Your father has a positive blood and your mother has o positive and you have a negative is this possible?
yes
Can a baby have A positive blood if the mother is O positive and the father is O negative?
No
If the father's blood type is A positive and the mother's blood type is O positive can the child's blood type be O negative?
No, because a baby gets their blood from their father, not their mother.
