In brief: Yes
Your blood group is based on presence of specific antigen on your red cells, if you have "a" antigen, you are "a" blood group, if "b" antigen then "b" blood group and if you neither have "a" nor "b" antigen, then you are "o" blood group.
Both "a" and "b" antigen are based on genetic make up. However, the ABO incompatibility that can lead to jaundice only happens when mother is "o" blood group.
