10 B Positive Blood Type Facts

B Positive Blood Type (B+)

1. The Third Most Common Blood Type

The B Positive blood type is extremely valuable where matching supply for the demand has been a constant challenge. However, it is the third most common blood type which is present in about 1 out of 12 individuals. This means an approximately 8.5% of the population has a B positive blood. But, note that not all of the ethnic groups share the same proportions of the B positive blood type. This blood type is present in about 9% in Caucasians, 18% in African American, 9% in Hispanic, and 25% 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 Positive 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.
