of the Interior About 200 years ago the Cherokee Indians were one tribe, or “Indian Nation” that lived in the southeast part of what is now the United States.
The Trail of Tears National Historic Trail commemorates the removal of the Cherokee and the paths that 17 Cherokee detachments followed westward.
Each biological parent donates one of their two ABO alleles to their child. Identical twins will always have the same blood type because they were created from the same fertilized egg (fraternal twins can have different blood types — again, providing the parents do — because they are created by two fertilized eggs).
Most of this is pretty straightforward. Two O’s make O blood type and an A and a B make AB.
As you undoubtedly know, there is no AO or BO blood type. This is because A and B are dominant over O. What this means is that an AO blood type looks like A in a blood test and a BO like B.
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them.
B positive patients can receive blood from B positive, B negative, O positive and O negative donors.
Platelets are not as type specific as red blood cells, meaning that most patients can accept platelets from donors with any blood type, regardless of the patient’s blood type. Since platelets only last for FIVE days, they are always needed by patients.
Transfusion with the wrong blood type can cause a severe reaction that may be life-threatening. If you have many blood transfusions, you are more likely to have problems from immune system reactions. A reaction causes your body to form antibodies that attack the new blood cells.
Blood types are determined by the presence or absence of particular antigens on the surface of red blood cells. There are eight main blood types: A positive, A negative, B positive, B negative, AB positive, AB negative, O positive and O negative. The positive and negative refers to your Rh type (once called Rhesus).
Type AB-positive
If you inject blood that’s incompatible with your blood type, your immune system might start to rip the foreign blood cells apart, triggering a cascade of reactions which potentially include blood clots clogging up your veins and killing you.
