No, it can't happen.
if one of the parents or both are +, the child will be Positive.
I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)

∙ 13y agoIf a person is blood type A, they can be genotype AA, or AO.
If a person is blood type O, they have to be genotype OO.
If a person who is A mates with a person who is O, they could have a child who is A or O.
So yes, a A- and an O+, could have an O- child.
Wiki User
∙ 13y agoYes, this is possible
and this could happen if both parents are +ve but with different alleles
to have a + blood type your alleles should be (Rh+Rh+) or (Rh+Rh-)
different alleles means the second option which is (Rh+Rh-) so :
(Rh+Rh-) X Rh+Rh-)
kids will be :
1-Rh+Rh+
2-Rh+Rh-
3-Rh+Rh-
4-Rh-Rh- --------> here is the negative O negative child with 25% to have it
Wiki User
∙ 11y agoYes; the most likely explanation for that is that both parents are phenotypically Rh positive and genetically Rh positive, and Rh negative.
This for general information purposes only. Blood groups are actually much more complicated. Individual circumstances can only be answered by a professional.

∙ 9y agoNo. Rh+ parents can only pass Rh+ on to their children.
Wiki User
∙ 14y agoNo. One of the parents would have to have a - gene, which isn't possable when you're both +
Wiki User
∙ 14y agoNo. Two Rh negative parents will give rise to a Rh negative child. So the child will be O negative.
Wiki User
∙ 12y agoNo, the child would have B positive because it is what both parents have.
Wiki User
∙ 12y agoi think it really depends on how somone raises the child
Wiki User
∙ 12y agoYes. Since the Rh factor is recessive if both parents have a copy of the gene they can have an Rh negative child.

Can 0 positive parents born an A positive child?
With genetic mutations during replication, anything is possible. But, in general two O negative parents could only have a child that is O negative. Conversely, two O positive parents could have a child that is either O negative or O positive.
If the mother has A positive blood and the father has O positive blood Would their child have A negative blood type?
get a bandana get beat up get money wear red. from saahir larosa = Answer = I'm going to say this in a sense that you have some clue about what I'm about to say. The child CAN indeed have a blood type of A negative, because the mother's Rh is Rr which is still considered Rh+ because the "R" is dominant over "r". If the father has the same Rh, the child has 25% of being Rh-(without doing dihybrid cross).
Can a person that has o positive blood and a person with a positive blood make a child that has a negative blood?
CAN TWO POSITIVE BLOOD TYPES MAKE a negative blood type
What blood types would produce a b negative child?
There is no single answer to this question. First, how does the child get type AB? The child needs to get an A gene from one parent and a B gene from the other, simple as that. This means neither parent can be type O because they would not be able to pass on the A or B gene (that is what O means, the absense of the A or B gene). If one parent is type A, the other must be B or AB. If one parent is B, the other must be A or AB. Also, both parents can be AB. In all cases, one passes on the A gene and the other passes on the B gene, that's it.Second, for the Rh factor (the positive and negative), the negative trait is recessive. This means the child must receive a negative gene from BOTH parents to display the negative phenotype. So the parents can be ANY Rh type. Why? Because it is a PAIR of genes, the GENOTYPE, that determines the trait. In the parents, they can be genotype +/- or -/+, meaning they have both the positive and negative gene and they can pass on the negative gene, but they will be POSITIVE Rh because that is the dominant trait. Of course, either parent could also be negative, -/- genotype, and they would certainly pass on the negative gene. So, you see, you cannot definitively type the parents in this case.
Can a mother with a negative blood and father with o positive blood have b positive blood group baby?
No. For a person to be "O" blood type, they have a phenotype of O, which can only come about if they have a genotype of OO. If both mother and father are O's then they have no B that they can donate to the baby.
Can O negative parents have an O positive child?
If they are both O negative, no, the child will be O negative.
Can parents who have B negative and O positive blood types have a child with O positive blood?
No, they will have a O negative child.
If two parents have A-negative and O-negative bloodtypes is it possible for their child to be A-positive?
No. Two rhesus-negative parents cannot have a rhesus-positive child.
Can a child be O negative if the parents are O positive and their are three grandparents who are O positive and one is B negative?
Yes.
Can parents with B negative and AB positive have a child with O negative?
No.
Can o positive and a positive parents have o negative child?
Yes. Since the Rh factor is recessive if both parents have a copy of the gene they can have an Rh negative child.
If both parents are A positive what usually will the child have?
A or O positive or negative
Can parents who are B negative and O positive have a AB positive child?
No
Can o plus an o negative have a child with type a blood?
No, if both parents are type O, the child must be type O. However, since one parent is positive and the other is negative, the child could be either positive or negative.
Can two parents with o positive have a child with a A negative blood type?
it is possible but the child can be a positive
Can an o positive father and o positive mother have a o negative child?
No. The child would be O and Rh+ just like the parents.
Can parents with a Rh negative and b positive have a child o or a positive?
yes
