Vatic Note: Well, I finally found another health site for medical professionals teaching them about blood types and factors. This is the beginning, and there will be more coming later as I go down this sites rabbithole. This is for all those who are RH negative and asked for more information. It shows why you always feel out of sync with others, since RH negative is clearly the minority type based on population studies, at least here in the states.
We have already dealt with characteristics that massive numbers of you world wide have commented and told us how that connected you to a much bigger population than you had known existed. In this blog below, we first put up, what blood is and its components and what their function is. We decided to do that since many people do not know this information and its foundational to the rest of the story.
RH Blood Type Genetics and Compatibility
By ADmin, Baylor, Scott and White Health site
Each blood component has a specific function. Blood is usually separated into its different components to treat various conditions in patients.
- Whole blood (which includes all the blood components) may be used to increase both red cell mass and plasma volume.
- Red cells carry oxygen to the body's organs and tissue. Red cells may be used to increase red cell mass as well as to prevent febrile reactions due to white blood cell antibodies.
- Platelets clot blood to help prevent bleeding and are used for patients with bleeding disorders.
- Plasma is the liquid that transports platelets and red cells through the blood stream. Plasma is used to treat some coagulation disorders.
A blood donor gives one pint of whole blood which is then filtered into red cells and plasma. A single blood donation has the potential to save up to two lives!
There are four main blood types: A, AB, B and O. AB positive is considered the universal recipient, and O negative is considered the universal donor.

- O Positive – 38%
- O Negative – 7%
- A Positive – 34%
- A Negative – 6%
- B Positive – 9%
- B Negative – 2%
- AB Positive – 3%
- AB Negative – 1%
Blood Type CompatibilityYour ABO blood type is based on the presence or absence of the A and B antigens on your red blood cells. The A blood type has only the A antigen and the B blood type has only the B antigen. The AB blood type has both A and B antigens, and the O blood type has neither A nor B antigen.
By the time you are six months old, you naturally develop antibodies against the antigens your red blood cells lack. For instance, a person with A blood type will have anti-B antibodies, and a person with B blood type will have anti-A antibodies. If you have type A blood, you cannot receive B blood because your body's anti-B antibodies will fight the B blood's B antigens. It is crucial we have all blood types available to our patients.

ABO Blood TypeEveryone has an ABO blood type (A, B, AB, or O) and an Rh factor (positive or negative). 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. For example, if an O gene is paired with an A gene, the blood type will be A.
For instance, a parent with O blood with 2 O genes and a parent with A blood with 2 A genes will have an A blood type child with one A gene and one O gene.
|AA||AA||AB||AA, AB||AO||AA, AO||AB, AO|
|BB||AB||BB||AB, BB||BO||AB, BO||BB, BO|
|AB||AA, AB||AB, BB||AA, BB, AB||AO, BO||AA, AO, BO, AB||BB, BO, AB, AO|
|OO||AO||BO||AO, BO||OO||AO, OO||BO, OO|
|AO||AA, AO||AB, BO||AA, AB, AO, BO||AO, OO||AA, AO, OO||AO, BO, AB, OO|
|BO||AO, AB||BB, BO||AB, AO, BB, BO||BO, OO||AB, AO, BO, OO||BB, BO, OO|
AO = A blood type
BB = B blood type
BO = B blood type
OO = O blood type
AB = AB blood type
Just as everyone inherits ABO genes, every person inherits one Rh factor gene from each parent. The Rh-positive gene is the dominant gene when paired with an Rh-negative gene.
|Negative/Positive||Neg/Neg, Neg/Pos||Neg/Pos, Pos/Pos||Neg/Neg, Neg/Pos, Pos/Pos|
Neg/Pos = Postive Rh factor
Pos/Pos = Positive Rh
