A Negative Blood Type (A-)
1. Rare Blood Type
It is very important to maintain sufficient supply of this blood type for it is rare. The A negative blood type is only present in about 1 out of 16 individuals. This means a few number with approximately 6.6% of the population has A negative blood. On the other hand, not all of the ethnic groups share the same proportions of A negative blood types. This blood type is present in about 7% in Caucasians, 2% in African American, 2% in Hispanic, and 0.5% in Asian.
2. Inheritance Patterns
The ABO gene found on chromosome 9 determines the ABO blood group system. A and B genes are codominant in relationship, making the expression of both antigens A and B when either alleles A or B is present. Blood Group A has an A antigen on red cells with the B antibody in the plasma.
How is A Negative blood type inherited?
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 AB, the child’s blood group will either be A or B.
If parental blood groups consist of A and A, the child’s blood group will either be A or O.
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 A and AB, the child’s blood group will either be one of A, B, or AB.
If parental blood groups consist of B and AB, the child’s blood group will either be one of B, A, or AB.
If parental blood groups consist of AB and AB, the child’s blood group will either be one of A, B, or AB.
3. Blood Type Compatibility: A- Can Only Receive A- and O-
A person with an A negative blood type has antigen A but with no Rh antigen on the blood. Having the presence of A antigen and absence of Rh antigen, A negative blood type can only accept A- and O-. Transfusions with any other blood group can trigger an immune response.
4. Blood Type Compatibility: A- Can Be Given To A-, A+, AB- and AB+
An A+ donor is compatible to donate blood to blood groups A-, A+, AB- and AB+ because of the presence of antigen A but the absence of Rh antigen in the donor’s blood. Male donors can give blood for up to 4 times a year while females can donate blood up to 3 times a year.
5. Plasma Type Compatibility: A Can Receive A and AB
Blood Type A doesn’t carry the A antibody, making blood type A group compatible to receive plasma from groups A and AB. However, blood type A plasma can only be given to type O and A recipients. A person can donate plasma every 28 days.
6. Has No 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. An A Negative blood type is Rh negative.
7. Sensitivity Towards Specific Diseases
Blood Type A is believed to influence natural risk and sensitivity towards diseases like cancer, allergies, diabetes and cardiovascular diseases. It’s best to plan regular screening for these conditions. A proactive mix of specialized dietary guidelines and lifestyle strategies can help maximize overall health in order to achieve increased longevity, greater vitality and mental clarity.
8. Association to Personality
Individuals with blood type A has been associated with specific personality traits. They are described to be analytical, inventive, detail oriented, creative, good listeners and sensitive to the needs of others.

This has a little bit of a story to it my question that is. In 1963 I received quite a bit of blood I had been run over by a car I had have many surgeries and people lined up to give me blood I found the receipts to those blood about 40 years ago and it had my blood type on it. It states I am A – to the 6th degree. I can find no one, and believe me I’ve asked everyone I can, what does it mean A – to the 6th degree. I feel this is important as I have a great number of medical problems and I have a few genetic issues that the answer to this question would be helpful. But this is back in 1963 and it seems all knowledge of this type of blood testing has disappeared. So please my question to you is do you know what it means that I have the blood type A – to the 6th degree?
I, too, am A-. The term “Sixth degree” may refer to kinship/consanguity. https://gato-docs.its.txstate.edu/jcr:6aa34d7b-82d4-4fbd-8602-34602fbbb70f/Degree%20of%20Consanguinity%20and%20Affinity%20Chart.pdf
