Answer: Rh boold factor is determined by the presnce or absence of a particular erythrocyte protein
Explanation:
The Rh factor is an integral protein of the membrane of red blood cells (erythrocytes) and, by its determination, the blood type RH + or RH- is detected, -regardless of the types of groups known as 0, A, B and AB- .
People who are RH + are those who have this protein in their red blood cells, and people with RH - refer to those who do not have the protein.
The Rh factor (Rhesus) was discovered by Karl Landsteiner and Wiener in 1940.
