ABO blood types can be complicated to understand. This is mostly due to the fact that the ‘O-type’ antigen is masked by the presence of an A- or B-type antigen. This is explained in the following chart, showing the different the genotypes that make up the blood types.
| Genotype (DNA) | Blood Type |
| AO or AA | A blood type |
| AB | AB blood type |
| BO or BB | B blood type |
| OO | O blood type |
For example, two O blood type parents can produce a child with only O blood type. Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
