1- There are four basic blood types in the ABO typing system:
- Type A blood and Type B blood have antigens and make antibodies to fight each other.
- Type AB blood.
- Type O blood doesn't have either type of antigen.
2- Blood type is inherited. It is passed genetically from your parents. And to donate your blood, all other donors and recipients must be safely compatible.
3- Donating or receiving blood is complicated .Type O blood, since it doesn't have antibodies or antigens for either type, can be donated to recipients with all four types of blood. Type AB, on the other hand, does not create antibodies for either antigen, can receive blood from all four types, but can but can only donate to other AB recipients.
