Expert Answer:

Dear student,
We cannot determine the blood group of the offspring in this case. This is because the genotype of the blood groups is not given, only the phenotype is given. The blood group A could be homozygous or heterozygous. So if the father is heterozygous, the offspring could have either blood group A or blood group O. So just with this information, we cannot determine the dominnat blood group.
