According g to science o blood group is dominant.
The O allele however, is recessive to both the A and B allele. Therefore, a person possessing both A and O alleles will have a blood type of A. Likewise, a person with both B and O alleles will be blood type B because B is dominant, and therefore, masks the O allele.

If A is considered to be dominant of O, possible combination of father will be AO and mother will be OO. Thus, daughter can be OO and hence have blood group O.
If O is supposed to be dominant over A, then possible combinations of father will be AA and mother will be AO or OO. So, the daughter can be OA and hence have blood group O.
From the given information, we cannot ascertain which blood group is dominant.
