Can an o positive blood type father parent an ab negative type child?

Before you make rash decisions, make sure all tests are confirmed. First, The AB negative mother should be able to give birth to A-.A+,B-,B+,AB-,AB+ child. The mother is the one that can not, if all the tests are correct, have an O child. The father, if he is A -, can only have A-,A+,B-,B+,AB-,AB+.O-,O+.
Now let me explain. There are two slots for A,B or empty(O). The father can be AO, or AA in this case. The mother is AB. She has to contribute either the A or the B, usually. Please notice the usually.
Final answer, no because of the mother's contribution unless there is a mutation.

∙ 14y agoThe father does not determine the blood type of the child. A baby is either the blood type of the mother or the father. I believe that in this case, the mother would have to be AB- if the child is AB- and the father is not. If not, there is something wrong in the equation.

∙ 15y agoThis is possible, depending on the mother.
Type O blood is a recessive trait, meaning that in order to have type O blood, you have to get an "O" gene from both mother and father. Types A and B are considered co-dominant. This means that when paired with an O gene, the blood type will not be O, but will be type B, if the genotype is OB or type A if genotype is OA. If paired together (genotype AB) the blood type will be type AB. Rhesus marker (the "positive" or "negative" so commonly heard after blood type) is a separate gene and is dominant. That means if you have one positive, the Rh will be positive.
So, for our situation above, we have to assume the father is type A negative, but his genotype is OA. If the mother of the child also has an O gene and is Rh positive, the resultant child could be O positive.

Can a blood type b negative man father a blood type a positive child?
yes, if the mother is either A positive or AB positive.
What blood type can a baby be if the father and mother are both type B positive?
The baby may be any of the following: * B positive * B negative * O positive * O negative
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
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.
Does same blood group of husband and wife affects in future?
It is actually better if you have the same blood group.
Can an O negative blood type father parent an B positive blood type child?
no
Can a parent with O positive and a parent with O negative have any affect on the child?
If the mother has type negative blood, and the father and child have type positive blood, the mother's blood may begin to attack the child's.
Can an B positive blood type mother and a O negative blood type father parent a B positive child?
Yes.
Can an o negative blood type father parent an o positive child?
Sure, if the mother is Rhesus (D) positive
Can a parent with a positive and a parent with ab positive have a child with a negative blood?
rarely can be
Can negative blood type parent and positive blood type parent have an Rh negative blood type child?
yes, absolutely
Can a parent with O negative blood type and a parent with A positive blood type have a baby with O positive blood type?
Of course!
Can an A negative parent and a A positive parent have a child who is AB negative blood type?
it can be rare only
Can a b neg father have an A pos son?
A father with the blood type can be b negative can have a child even a son that is A positive. The blood of a child comes from one or the other parent. If the mother is A positive the child can be as well.
Can a o negative blood type father have an a positive baby?
Yes, as long as the mother's blood group is Rh positive, the baby can be Rh positive. Only one parent need be Rh positive for this to occur.
Is it possible for a mother to have a positive blood type and father b positive to have a baby with ab negative?
Yes -- There is not one gene that determines blood type. The father can be heterozygous for the A blood type. This just means that the father has one A gene and one O gene. Since the A gene is dominant, the blood from the father tests as A. A separate gene determines the positive and negative part of the blood grouping. This is the RH factor. Again the father can have one gene that is positive and one that is negative, positive is dominant. Same analysis for the mother, mixed B and O genes with B as dominant, positive and negative for RH factor, positive dominant. The egg from the mother could contain the B and RH negative (50% chance of each). The sperm from the father could contain the A and RH negative. Thus the baby would be AB negative (no positive from either parent).
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.
