10 O Positive Blood Type Facts (2024)

O Positive Blood Type (O+)

1. Most Common Blood Type

The O positive blood type is the most common and incredibly an important donor in maintaining adequate blood supply. It is present in 1 out of 3 individuals. This means approximately 37.4% of the population has O positive blood.However, not all of the ethnic groups share the same proportions of blood types. O positive blood type is about 37% in Caucasians, 47% in African American, 53% in Hispanic, and 39% in Asian.

2. Inheritance Patterns

The ABO gene found on chromosome 9 determines the ABO blood group system. O genes (or alleles) do not produce antigens A or B, thereby are called silent alleles.Blood Group Ohas neitherA or B antigen on red cells but with both the A and B antibody in the plasma.

How is O Positive blood type inherited?

If parental blood groups consist of O and O, the child’s blood group will be O.

If parental blood groups consist of O and A, the child’s blood group will either be O or A.

If parental blood groups consist of O and B, the child’s blood group will either be O or B.

If parental blood groups consist of A and A, the child’s blood group will either be O or A.

If parental blood groups consist of A and B, the child’s blood group will either be one of O, A, B, or AB.

If parental blood groups consist of B and B, the child’s blood group will either be O or B.

4. Blood Type Compatibility: O+ Can Be Given To O+, A+, B+ and AB+

Being an O+ donor makes the person the type of individual to hold being the most ideal red blood benefactor. Individuals with an O+ blood type can be a red blood cell donor to blood types O+, A+, B+, and AB+.

5. Plasma Type Compatibility: O Can Receive O, A, B and AB

Blood Type O carries both antibodies, making blood type O group compatible to receive plasma from groups O, A, B and AB. However, blood type O plasma can only be given to type O recipients. The individuals who are compatible inreceiving platelets from an O+ donor are O+ recipients.

6. Has an Rh Factor

Rh Factor is an additional marker in the blood. This can be classified as either Rh positive or Rh negative. This marker is only used for genetic differences. O Positive blood type is Rh positive. Also read about O Negative Blood Type.
