Can a father who is O and a mother who is B have a child who is AB?

No. In the ABO blood type system, a parent with the blood type O and a parent with the blood type B can not have a child with the blood type AB. A person with blood type O has no A or B antigens on the surface of their red blood cells. A person with blood type B has a B antigen on the surface on their red blood cells. Neither parent has the gene to code for antigen A so the child of both parents would not be able to have a blood type involving the A antigen, such as blood types A or AB. A father with O blood type is likely not the father of an AB child (+ or -) with a B- mother.
But blood tests for paternity are not 100% certain. In addition, people often mis remember their blood type.
The best paternity test is a DNA test.

∙ 14y agoNo. Blood group of a person is controlled by 2 alleles, one from each parent. The allele for blood group AB is A and B, while that for group O is O and O. In this case, the only possible combinations for the offspring are AO or BO. As O is recessive, the blood group of the offspring must be either A or B, definitely not AB.
To produce a child of blood group AB, the blood groups of the parents must be:
1. AB x AB (both AB)
2. AO x BO (1A and 1B)
3. AA x BO (1A and 1B)
4. AO x BB (1A and 1B)
5. AA x BB (1A and 1B)

∙ 9y agoYes, parents with type B and type AB blood can have a child with type AB blood. If the child has a negative Rh factor, both parents must also have a negative Rh factor.

If mother is B- and father B plus can child be AB?
If my mother is b- and my dad is b+ could there be a child ab- please
Can a mother has A positive blood type and a father has AB positive and the child has B positive?
Since both parents are Rh+, the child will also be Rh+.If the Mother is A0+ and Father is AB+, the child will be: AA+ AB+ AO+ or BO+ So yes this does produce a B+ child.If the Mother is AA+ and the Father is AB+, the child will be AB+ or AA+ neither of these is B+ so this doesn't produce a B+ child.
Can Mother B positive Father is AB positive Can child be o negative?
A blood type O child would be impossible from this match. An AB parent must give an A allele or a B allele, and both alleles are dominant. If mother is homozygous B (meaning both alleles are B's), and father is AB, child can be either B or AB. If mother is heteroygous B (meaning one B allele and one O allele), and father is AB, the child can be either A, B, or AB.

when father have ab mother 0 plus child have?
A or B
Can AB father and B Mother have one A child and one B child?
they can only get either AB or B blood type children.
If mother and father is A blood group can child be B positive?
If the mother is A, and the father is A, then the child will only have A antigens and will thus be blood type A. If father or mother are AB, then the child can end up with AB, A, or B blood type. http://en.wikipedia.org/wiki/Blood_type
Can a child be B positive if mother is O negative and father A positive?
No, the father would have to have B or AB.
Can a type AB child have a father with type A blood?
Yes, if the Mother is type B or AB.
Can a A Negative Father and an AB Positive mother have an A Negative child?
The child will be A or B or AB, Rh+ or Rh- . So yes, the child can be A-.
Can an AB mother and an O father have an O child?
No. An AB father does not have an O allele and can only pass on an A or B allele to his child. So the child will either be type A or type B, but not O.
Can Mother B positive Father is AB positive Can child be A positive?
yes
