Detailed explanation-1: -The Rh factor is an inherited protein that can be found on the surface of the red blood cell. If your blood type is positive, then your blood cells have the Rh protein. If your blood type is negative, then your blood cells lack the Rh protein.
Detailed explanation-2: -The Rh antigens are expressed as part of a protein complex in the RBC membrane. This complex is only expressed in cells of the erythroid line, and therefore Rh antigens are only expressed in RBCs.
Detailed explanation-3: -There are 5 main Rh antigens on red cells – C, c, D, E, e. The most important of these is the Rh D. Having the D antigen on the red cell gives you the positive (+) and lacking it gives you the negative (-) after the letter A, B, AB or O.
Detailed explanation-4: -Rh factor (or Rhesus factor) is a type of protein on the outside or surface of your red blood cells. You inherit the protein, which means you get your Rh factor from your biological parents. If you have the protein, you’re Rh-positive. If you don’t have the protein, you’re Rh-negative.
Detailed explanation-5: -Two separate genes for the Rh system are found on chromosome 1. One gene, RHD, encodes for the D antigen. Individuals with the D antigen present on their red blood cells are labeled as “Rh (D)–positive.” Those who do not have the D antigen are labeled as “Rh (D)–negative."
