10 B Negative Blood Type Facts

B Negative Blood Type

1. The Second Rarest Blood Type

Negative blood types are actually rarer compared to positive types. The B Negative blood type is one of the rarest and second to AB Negative, being the rarest of the blood types. Being rare, it is extremely important to maintain sufficient supply for this blood type considering that it’s one of the hardest to collect to make sure it is enough. It is only present in 1 out of 67 individuals. This means an approximately 1.5% of the population has a B negative blood. Note however that not all of the ethnic groups share the same proportions of the B negative blood type. This blood type is present in about 2% in Caucasians, 1% in African American, 1% in Hispanic, and 0.4% 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 B has a B antigen on red cells with the A antibody in the plasma.

How is B Negative blood type inherited?

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 O and AB, the child’s blood group will either be A or B.

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 B, the child’s blood group will either be O or B.

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: B- Can Only Receive B- and O-

An individual with a B negative blood type has antigen B but with no Rh antigen on the blood. Having the presence of B antigen and the absence of Rh antigen, B negative blood type can only receive B- and O-. A transfusion with the usage of any other blood type can initiate an immune response.

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

A B- individual can be donor to blood groups B-, B+, AB- and AB+. This is because of the presence of antigen B and the absence Rh antigen in the donor’s blood. Male individuals can donate blood for up to 4 times each year while females can have it for up to 3 times a year.

5. Plasma Type Compatibility: B Can Receive B and AB

Blood Type B doesn’t carry the B antibody, making blood type B group to be compatible in receiving plasma from groups B and AB. However, blood type B plasma can only be given to type O and B recipients.

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. A B- blood type is Rh negative. B Negative blood type has certain risk involved which is common to all Rh negative blood groups. This happens during pregnancy when mother is Rh Negative and Fetus is Rh Positive.

7. Primary Challenges

There can be challenges that Blood Type B individuals may face. The blood type is likely linked with sensitivity to B specific lectins in some foods, higher than normal cortisol levels in relation to stress, vulnerability to autoimmune diseases, and susceptibility to slow growing viruses like lupus. However, a healthy blood type b individual can have fewer risk to diseases and believed to be more physically fit than other blood types.

8. Blood Type B Personality

Individuals with blood type B has been described to learn best through listening, reflecting, and interpreting. They are also associated to being original, flexible, creative, mystical, idealistic, subjective, globally-oriented and people-oriented.

9. Diet Recommendations

It is encouraged for blood type B individuals to follow have highly beneficial foods like eggs, low fat dairy, green vegetables and beneficial meats. On the other hand, foods that affect metabolism productivity like wheat, corn, peanuts, sesame seeds and tomatoes should be avoided. Chicken consumption should also be replaced with foods like lamb or goat. This is because chicken contains a Blood Type B Agglutinating lectin which may cause harm to the bloodstream resulting to immune disorders or strokes.

10. Exercise Recommendations

Providing balance to meditative activities with physical activities is important in blood type B individuals. This will help maintain balance for mind and body challenges. It should not be aerobically intense but instead a mixture with mental challenges. Great examples would be hiking, cycling, golf, tennis and martial arts.
