Abstract
Ever since blood typing has been investigated, many new medical advancements have
been achieved, saving the lives of many. Not only does blood typing save lives, it can determine
who a father is of a child, and it could lead to more medical advances. In the experiment, we
needed to determine who the father of a baby is by comparing its blood to the mothers, and two
possible fathers. In the procedure we took the four different samples of synthetic blood and
placed them into a depression on the blood type slide. We added anti A, B, and Rh serum to the
samples to determine what type of blood the person had. The blood showed the Puck more likely
the father compared to Finn. The experiment was very simple and it would be difficult to make
an error. Not only did the experiment explain how blood typing works, but it gave you a real life
example, even if a television show isn’t real life.

Genetics’ Formal Lab Report
Ever since Pope Innocent VIII received a blood transfusion but then later died, blood
typing and blood transfusions has been investigated. Back then some trials and testing were
banned because of a high death rate because it wasn’t known that your body would reject
different blood types. But fortunately for us, Karl Landsteiner, the most important person in the
area of blood transfusions, discovered the three different blood types found in humans, A, B, and
O. From that birthed the same blood types we have today, A+, A-, B+, B-, AB+, AB-, O+, and
O-. Since then many lives have been saved by blood transfusions. But blood typing isn’t only
used for blood transfusions; it can also determine parents of a child by blood types and whether
or not the child is Rh+ or Rh-. If you have a + blood type, then you have Rh antigens, you don’t
have them if you are Rh-. All these factors are important if you are getting a blood transfusion
because you don’t want to get the wrong type of blood in your system. These factors sum up the
importance and the basis of blood typing and transfusion. Without all this, we wouldn’t have the
amazing medical technology like we do today.
In the blood typing lab we needed to figure out who the father of a baby was using the
known blood types of the mother, possible fathers, and child. If Puck is the father of the child,
then his blood type and Quinn’s blood type will make possible genotypes which the child has
because the child needs a trait, dominate or recessive, from each parent.

Experiment
Materials

Blood type slide

10 toothpicks

Anti-A serum

Anti-B serum

Anti-Rh serum

4 blood samples
Procedure
After the materials were prepared, we added a drop of synthetic blood into each
depression in the first row on the slide. We repeated this step with each type of blood. Then we
added the anti serums and mixed them with a toothpick. We then recorded if the blood clumped
together or not. We analyzed the results, if the blood clumped together, that meant that the blood
was positive for whatever antiserum was used.

Conclusion
The experiment showed that Quinn, or blood sample 1, was positive for Rh, and she had
blood type A. All of those blood samples had clumped, while the others stayed a liquid. Puck’s
blood, blood sample 2, was positive for Rh and he is blood type B. Blood sample 3, Finn, was
negative for Rh, but both A and B antiserums clumped, which means he is AB-. The baby’s
blood, blood sample 4, was only positive for Rh, which means the baby is O+. These results
follow my hypothesis, that Puck was the father of the baby, not Finn.
This experiment left little room for error, and it helped with understanding how blood
typing works. It was a very simple procedure , all you had to do was take the blood samples and
add the antiserums to find out if the blood type was positive for the antiserum or not, to do that
you have to see if it clumps or not. I wouldn’t change the procedure because it was very simple,
but if I wanted to add anything to the procedure I would add something more to investigate and
make the lab a little more complex. I would like to see something more, though I am unsure what
to add because the simple lab covered a lot.
