Actually, yes. The father may be heterogeneous type B - that is, he has a recessive gene for type O along with his dominant gene for type B - and both parents may be heterogeneous for the Rh trait, where being Rh positive is dominant. Since the mother is homogeneous for the O type, there's a 50% chance that she will produce a child with type O blood when her partner also carries one O gene. Assuming both parents are heterogeneous for the Rh trait, each child they produce has a 25% chance of being Rh negative. Since half those Rh negative children would have blood type B, this means that about 12.5% of the time these particular parents would produce a child with O- blood.

∙ 15y agoYES = Rh Positive (Rh+) and Negative (Rh-) Blood Types = The Rh (+/-) factor is inherited separately from the ABO blood types. Similarly to the masking effect of the O gene in ABO blood types, the Rh negative (Rh-) gene is also masked by the presence of a Rh positive (Rh+) genotype. Therefore, a person may have a Rh + blood type and can still have an Rh - gene (See the chart below). Furthermore, 2 parents with Rh + blood types can have a child with Rh - blood type. Genotype (DNA) Blood Type(+ , -) or (+ , +)Rh +(- , -)Rh -

∙ 14y agomost likely not. i think AB positive kids come from parents who are A positive and B positive.
Wiki User
∙ 14y agoI'm not sure how negative or positive is determined, but a B mother and O father can have a B child.

∙ 15y agoNo, O parents can only have O children

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.
Can a father with A Positive blood have a child with A Positive blood?
It depends. If the mother of the child is A positive as well, the child will be A positive. This is also true if the mother is a type O. It wont be possible if the mother is B positive, since the child will be AB positive (the blood types are codominant).
Can a father with o positive blood have a child with A positive blood?
If the father is O and the mother is A, the child can end up either A or O.If the father is O and the mother is AB, the child can end up either A or B.
Can a mother with o positive blood and the father has b positive blood have a child that is a positive?
no, it's impossible.
If the mother has B positive blood and father has A positive blood what is the blood type of the child?
A or B or AB
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.
If mother is B positive and father is A positive what will be the blood group of child?
Blood type A/B
If the mother is o positive and the father is a positive what would the child's blood type be?
A+
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.
If the mother has O positive blood and the father has A negative blood what should the child have?
a-
