Why is type O blood so common if it is recessive?
The gene for type O is ‘recessive’, because if you have one gene for O and one for A, then you still end up with A antigens on your cell membranes, and the same goes for O and B. In order to be group O, you need both parent cells to be O. But group O is still more common simply because it is the ancestral form.
Why is O+ most common?
The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood. For more about plasma donation, visit the plasma donation facts.
Is type O blood dominant or recessive?
ABO Blood Type Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.
Why is o the universal donor?
People with type O- blood are called universal donors because their donated red blood cells have no A, B or Rh antigens and can therefore be safely given to people of any blood group.

Why is O positive special?
Type O positive blood is given to patients more than any other blood type, which is why it’s considered the most needed blood type. Type O positive blood is critical in trauma care. Those with O positive blood can only receive transfusions from O positive or O negative blood types.
Do Type O blood types get Covid?
Blood type O seems to have the lowest risk. Yet these risks are relative, meaning people with type O blood are not immune to COVID-19. “We do know that people of all types can get infected with COVID-19,” says cardiologist Daniel Anderson, MD, PhD.
