MEDICAL PHYSIOLOGY

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 protein on the surface of your red blood cells determines your blood type. Each blood type also has a positive or negative factor. The positive or negative next to the blood type is your Rh factor. Your Rh factor doesn’t cause problems or hurt your health in any way.

Detailed explanation-3: -Your Rh type is determined by a different pair of genes to the ones that determine your ABO blood type (again, one inherited from each parent). Blood is either Rh-positive or Rh-negative, depending on whether certain molecules are present.

Detailed explanation-4: -The RhD protein encodes the D antigen. Two genes, RHD and RHCE, encode the Rh antigens. The Rh genes are 97% identical, and they are located next to each other on chromosome 1. The D/d polymorphism most commonly arises from a deletion of the entire RHD gene.
