It depends on the genotype of the parents: If they are AO and BO the child could be all of the 4 ABO-Bloodtypes: AO (= bloodtype A) BO (= bloodtype B) AB (= bloodtype AB) OO (= bloodtype O) If they are AA and BB the child could only be bloodtype AB If they are AO and BB the Child could be AB, or B (BO) If they are AA and BO the child could be AB or A (AO) In short, when the genotype is not given, the child can have any of the ABO-Bloodtypes
