Answer:

Blood types O, A, and B are possible for the father.

Step-by-step explanation:

Since the mother has type A blood, there are two possible genotypes that she can have: AA or AO. Since her son has type O blood, he only has one genotype: OO.

For blood types,

Type A - AA or AO

Type AB - AB

Type B - BB or BO

Type O - OO

* A and B are dominant over O.

Now we have to do crosses between the mother and the father:

AA mother with AB father: child with type AA or type AB blood

AO mother with AB father: child with type AA, AO, AB, or BO blood

AA mother with OO father: child with AO blood

AO mother with OO father: child with AO or OO blood

AA mother with AA father: child with type AA blood

AA mother with AO father: child with type AA or AO blood

AO mother with AA father: child with type AA or AO blood

AO mother with AO father: child with type AA, AO, or OO blood

AA mother with BB father: child with type AB blood

AA mother with BO father: child with AB or AO blood

AO mother with BB father: child with AB or BO blood

AO mother with BO father: child with AB, AO, BO, or OO blood

The father can have blood types O, A, or B.

Hope this helps.
