8.2.23-LS Antigek in Blood
Human blood can contain the A antigen, the B antigen, both the A and B antigens, or neither antigen. It may or may not also
contain the Rh antigen. Blood is called type A-positive if the individual has the A and Rh but not the B antigen. A person having only
the A and B antigens is said to have type AB-negative blood. A person having only the Rh antigen has type O-positive blood. Other
blood types are defined in a similar manner. In a certain hospital, the data, shown to the right was recorded. Use a Venn diagram
to answer parts (a) through (h) about the blood samples. For parts (d) through (h), the presence or absence of antigens determines
blood type
