Introduction to Blood Typing
A. Blood Types- When an individual is born, he/she receives a gene for
blood type from her mom and a gene for blood type from her dad.
These genes code for proteins or antigens on your Red Blood Cells that
identify your blood type. These proteins are also very specific. If you
were to be given the wrong blood protein (different then your own),
your body would attack this foreign blood type (via its antibodies- part
of your immune system) and cause your blood to coagulate (agglutinate)
or clot which could lead to death. Blood proteins types: A & B are
dominant and O is recessive.
1. AA or AO- your blood type is A. You cannot receive type B
blood. You can receive type A or O
2. BB or BO- your blood type is B. You cannot receive type A
blood. You can receive type B or O.
3. AB (rarest blood type) - your blood type is AB. You can receive
any blood type, A, B, AB, or O (universal receiver).
4. O (most common blood type) - your blood type is OO. You can
only receive type OO blood (universal donor).
Purpose- By applying your knowledge of blood types determine whom the
father of David Smith is knowing that Jane Smith is his mother.
Materials- toothpicks, wax pencils, microscope slides, simulated Anti-A
Antiserum, simulated Anti-B Antiserum, and simulated blood samples for
Jane Smith, John Smith, David Smith, and Wiley Smith.
Procedure (4 per group)
A. Each team takes 4 slides- label the top of each slide with the initials of the
individual being tested, divide the slide with the wax pencil in half,
labeling one side A and one side B.
Jane Smith
A
B.
B
Place 1 drop of Anti-A serum in the “A” box and 1 drop of Anti-B serum
in the “B” box on your slide.
C. Place 1 drop of the person’s simulated blood being tested on both Antisera.
D. Mix blood and Anti-sera with a toothpick for 2 minutes. Be sure to use a
different toothpick for each mixing (you do not want to contaminate the
blood).

E. Observe agglutination. If agglutination occurs in A only the person has
type A blood. If agglutination occurs in B only, the person has type B
blood, if agglutination occurs in both A & B, then the individual has type
AB blood, and if no agglutination occurs, the individual has type O
blood.

Questions
1. Who is the father of David Smith? _________________________________
2. How do you know? ______________________________________________
________________________________________________________________
3. Using your knowledge of Punnett Squares, list all the possible genotypes
of the children for Jane and John Smith. Show work.
4. Using your knowledge of Punnett Squares, list all the possible genotypes
of the children for Jane and Wiley Smith. Show work.
5. Why do you think red blood cells have specific antigens on them? ______
_________________________________________________________________
6. If John knows his father had type B blood could Wiley be his long lost
brother and why? Hint: remember if one is type B blood, they can either
be BB or BO. Try using Punnett Squares to help you out._______________
