Yes, an O positive father can have a B positive son. The son would inherit one B allele from the father and one O allele from the mother, resulting in a B positive blood type.

Father has o- blood type son has a- does that mean they're not father and son?

No, it is still biologically possible for a father with O- blood type and a son with A- blood type to be related. The A- blood type could have been inherited from the mother or through other familial relations. Blood types are inherited from parents, but multiple genetic factors can influence blood type.

My child has O positive blood and I have B positive blood what blood type is the father?

Based on your child having O positive blood and you having B positive blood, the father could have blood type A or AB with a positive Rh factor. This is because both blood type A and AB are compatible with B to produce an O blood type in your child.


What blood type would a child be with a AB neg mother and O positive father?

The child would most likely have either blood type A positive or B positive. A child inherits one blood type allele from each parent, so with an AB negative mother and an O positive father, the child could receive the A allele from the mother and the O allele from the father, resulting in blood type A positive. Alternatively, the child could receive the B allele from the mother and the O allele from the father, resulting in blood type B positive.


What would a child be if the father was B positive and the mother was O positive?

The child could be either B positive or O positive. The child inherits one blood type allele from each parent, so they could inherit the B allele from the father and the O allele from the mother (resulting in B positive blood type) or inherit an O allele from both parents (resulting in O positive blood type).
