yes because maybe the babys mom did. or maybe other generations of the babys parents did. or on and on.
The father's blood type can be O, A, or B.
A
The child would have A plus blood type since A blood type is a dominant trait while O blood type is a recessive trait
A+
The father's blood type would have to be A. This is because O is a recessive blood type and needs two O's to produce a child with and O blood type. So if the daughter is an A blood type so must her biological father's.
ab+ a+ b+
Yes, as long as the mother has B in her blood type (either B or AB), the father can have O.
A child with a parent with A positive and a parent with type O blood may be type A or type O. Without knowing the Rh factor of the second parent, it's not possible to say whether the child may have Rh negative blood.
The blood types of the parents have little or no bearing on whether they can conceive a child.
Yes, the child's blood type can be B if the father has o.
The child inherits one allele from each parent for their blood type. You said that the mom is o+ and so is the child. Therefore: The father cannot have the following blood type genotypes: AB+, AB-, AA+, AA-, BB+, or BB-. The father's blood type genotypes can be: Ao+, Ao-, Bo+, or Bo-.
An A blood group father can have an O type child. If he does, then he is heterozygous for type A.
