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 O has neither A 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.

  1. The paragraph on how we get really angry is mostly untrue for a lot of people, or maybe just me. Id try adding: some are pretty chill or something. lol.

    1. I wondered about that, myself, Cloe. My “temper tantrums” aren’t directed outward; rather, I hold on to negative feelings for quite some time. This, in turn, colors my view of the specific situation and subsequent actions, until I get straight with myself and resolve it emotionally. So, this holds true for this O+.

    2. How dare they catagorize me by my blood type it’s extremely irrational to say I have tantrums and the like. Outrageous why the unmitigated gull.

    3. This could explain why I’m such a fireball. Maybe I got yours, and mine. I use it for positive expression in martial arts and generally excel. I’m usually more energetic and aggressive than my sparring partners and have been nicknamed “Animal.” Fight or flight isn’t always a bad thing. My reaction time is fast and effective. Thank you type O

  2. I have cut out wheat and grains, eat a lot of meat and health has improved.
