O blood has no major proteins that A and B blood have. For example: If someone had B blood with its specific proteins, this person cant receive A blood because it has the specific A blood proteins that will cause bad clotting to stop it. O blood (with no different proteins) wont affect any blood.
A person with Type O can donate to any other blood type, but can only receive blood from another Type O person. A person having blood group O (with absence of Rh-factor) only can donate his blood to any other individual. Rh or Antigen-D is a factor which decides the positivity or negativity of the blood, so the blood group O-negative is considered the universal donor, as it does not effect any of other blood groups.
Blood group A can donate and receive blood from blood group A. Blood group B can donate and receive blood from blood group B. Blood group AB can donate only to blood group AB and receive from any other blood group (they are universal recipent) Blood group O can donate to any other blood group ( they are universal donor) and can receive from only blood group O.
O negative
People with O negative blood are often referred to as "universal donors" because their blood can be transfused to patients with any blood type. Therefore, anyone can donate O negative blood to individuals in need, regardless of their own blood type.
Blood type O- can only receive blood from others with blood type O-.

Yes, a person with blood group O can donate blood to someone with blood group AB, as type O is considered a universal donor. In situations where an exact match is not available, such as in an emergency like heart surgery, transfusing type O blood is often the safest option to prevent any compatibility issues.
The blood group O positive(O+) specifies that the person can donate his/her blood to any other person of same or different blood group. But, O+ can accept blood only from a person having same blood group (i.e O+) and not from any other group.
Anybody can possess the Rh O-Negative, alias the 'Royal Blood', as it is not restricted to royalties.The royal blood is a specific blood group. It is the Rh O-Negative. It is a very rare group. So rare that when it was discovered to be running in the veins of a royal family and their descendants, it was named the 'Royal Blood'. Anybody can possess the Rh O-Negative, alias the 'Royal Blood', as it is not restricted to royalties.The Rh O-Negative is a Universal Donor, i.e. someone possessing this blood group can donate his/her blood to anyone, irrespective of their blood groups. This is a sort of blessing, as you can save anybody. The big problem with it is that the Rh O-Negative recipient can only receive blood of Rh O-Neg type which is, as I said before, very rare.
O blood type is universal becuase anybody can take it whether you are O, A, B, or AB. O mixes with anything and does not coagulate. If you are an O blood type, you may not receive any other blood type or your blood will clot.
Nope - O negative is the only group that can be safely given to the patient if their blood group is unknown.
