Is O+ or O universal donor?
Group O can donate red blood cells to anybody. It’s the universal donor. Click on a blood type below to learn more. Group O can donate red blood cells to anybody.
Why are there 4 blood types?
There are four main blood types: A, B, AB and O. The system for classifying them came about in order to allow safe blood transfusions. Like all cells, red blood cells have molecules on their surface called ‘antigens’. People have different antigens, depending on their genes.
What are the four main blood types and how do they exist?
The presence or absence of A or B antigens gives us four main blood types:
- A type blood has only A antigens on red blood cells.
- B type blood has only B antigens on red blood cells.
- AB has both A and B antigens on red blood cells.
- O has neither A nor B antigens on red blood cells.
What are the 8 different blood types?
People are probably most familiar with these types because they include the eight common blood types: A-positive, A-negative, B-positive, B-negative, AB-positive, AB-negative, O-positive, and O-negative.

What is the best blood type to have?
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there’s a limited supply of the exact matching blood type. That’s because type O negative blood cells don’t have antibodies to A, B or Rh antigens.
What are the genotypes for the four blood types?
There are 4 blood types: O, A, B, AB. A and B are dominant genes. O is recessive. A and B are equally dominant so that when they get together they create a new blood type: AB.
Which is the universal donor blood group, O+ or O-?
Blood group O is known as the “universal donor” because it has no antigens on its red blood cells and can therefore be safely given to any blood group. Blood Group AB is known as the “universal recipient” because it has no antibodies in its plasma and so can safely receive blood from any other blood… group.
