No they cannot. They can only have a child with type A or type O blood.
Yes, it is possible for a blood type B negative man to father a blood type A positive child. The ABO blood type system is inherited from both parents, with each parent passing on one of their two ABO genes to their child. This means that the child could inherit an A gene from the mother and a B gene from the father, resulting in a blood type of A positive.
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.
NO
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.
The genotype of the man is A negative/O negative inheriting the A neg from his mother and O negative from his father. [Father's genotype is B positive/O negative. Mother's genotype is B positive/A negative.]
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.
yes
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
a-
No
more than 99% not.
There is a 75% chance the child will be A negative, and a 25% chance the child will be O negative.
yes.
No.
yes.
The blood would be A+, the child's is always pretty much what the Father's is.
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.
