Answer:
The possible genotype of the father will be AA or AO meaning of type A blood
Explanation:
The ABO blood group system can be regarded as the classification of human blood which is determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells (erythrocytes). An individual may therefore have type A, type B, type O, or type AB blood.
For a mother to be of type O blood, it means her genotype is OO and is inherited in the recessive form. The infant of type A can have a genotype of AO or AA. Thus, the possible genotype of the father will be AA or AO meaning of type A blood
