A person must inherit two recessive Rh negative genes, one from each parent, to have Rh negative blood. The gene for the RhD antigen is dominant, meaning that only one copy is needed for the trait to be expressed.
Understanding Rh Antigen Positive and Negative Differences
Genetics and Inheritance The Rh factor is inherited genetically, following a dominant-recessive pattern. While the ABO system provides the primary framework for blood typing, the Rh factor, specifically the presence or absence of the D antigen, adds another vital layer of complexity.
Conversely, if the antigen is absent, your blood is Rh negative. If that same person receives another transfusion of Rh positive blood, the newly formed antibodies will aggressively attack the donor cells, causing a potentially life-threatening hemolytic transfusion reaction.
Understanding Rh Antigen Positive vs Negative Differences
This stark contrast highlights the evolutionary pressures and genetic drift that have shaped these populations over millennia. An Rh negative individual who receives Rh positive blood will develop antibodies against the D antigen as a defensive immune response.
