Hard to say.: Mother's blood type needed too.

Any: It depends on mom's blood type as well. This would be a great time to brush up on mendelian inheritance. Dad can be genotype aa or ao, and there are a couple of unusual alleles as well with which you needn't be concerned for everyday questions like this.
