These are two resources to help in teaching blood type genetics.
1) For students completing a real or simulated blood-typing lab, there is a pre-lab table. This helps students organize their knowledge of the different antigens on red blood cells and antibodies in blood serum, and predict what they will see in the lab as results for each blood type.
2) For students studying blood transfusions, there is a table for identifying which blood types are compatible. This requires that students already understand the antigen-antibody system. There is also a table of data to inform students about how common different blood types are. This could serve as a springboard for discussion about why come types are more common than others.
