A man with any blood type by AB can father a child with type O blood. A parent heterozygous for type A or B may have a child with type O.
Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
Father can be A, B, or O.
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.
Yes, the child's blood type can be B if the father has o.
Yes.
Yes, they can.
Yes, they can.
The father's blood type can be O, A, or B.
Yes. The father's blood type must be oo. The mother's blood type could either be Ao or AA (both of these are blood type A). If the mothers blood type is Ao, she could give the o gene to the baby, resulting in the baby being type oo (or type o). (In order to have blood type o, you must have an o from your mother and an o from your father.)
An A blood group father can have an O type child. If he does, then he is heterozygous for type A.
most likely O.
Yes.
