Answer:
85% of the the U.S. population has Rh+ blood
Explanation:
Out of the total population of USA, nearly 15% of the individuals are having Rh negative blood.
The remaining population has Rh positive blood which is equal to 100-15%
or 85%.
Thus, 85% of the the U.S. population has Rh+ blood
Blood antigens are actually surface proteins found embedded on the red blood cell membrane. The blood type determines the surface antigen and the plasma antibodies found in the blood. If a person is type AB Rh negative, then the person has both A and B antigens on the red cell membrane but without the Rh antigen. On the other hand, the same person has no anti-A or anti-B antibodies in the plasma but has anti-Rh antibodies.

<h2><em><u>Base</u></em><em><u> </u></em><em><u>isolated</u></em><em><u> </u></em><em><u>system</u></em></h2>
