3. Genetic Cross for Blood Types

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

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

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

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

8. Agglutination  The antigen and the antibody GLUE together!

9. Blood Typing!  Using antibodies to discover blood types

10. ABO blood typing
