Presentation transcript:

Red Blood Cells  Surface has “Markers” called Antigens

Genetic Cross for Blood Types

Red Blood Cells  Surface has “Markers” called Antigens  A and B are dominant over O  A and B are Co-dominant

Rh Antigen  Red blood cells can also have another antigen called the Rh antigen

Antibodies  Each blood type has an opposite antibody to its surface antigens

Rh Antibody  Rh + cells have NO Rh Antibody  Rh – cells have the Rh Antibody

Agglutination  The antigen and the antibody GLUE together!

Blood Typing!  Using antibodies to discover blood types
