GENETICS WEBQUEST:
Blood Types
Greetings, genetics students. In this webquest you will explore the
genetics of human blood types. (You will work in groups of three on each
computer if needed.) Use this guide as a record of your travels and
accomplishments as you navigate the site. The force will be with you, always.
Begin by navigating to http://www.biology.arizona.edu/ . Select the “Human Biology” link in
the upper left hand corner under “Activities”. Click on “Blood Types” to begin.
Read the introduction carefully. The monohybrid cross tutorials (click on problems 11 & 13
before you move on) are essential reading at this point. Once you have studied this material
completely, click on the “ABO markers” button to see the next page.
Read the "The Human ABO markers: The A, B, and O alleles tutorial page." If you know your
own blood type, write that here __________. (Put AB if you do not know your own.)
Click on the “Blood Types/Genotypes” button to continue.
Read the “How are blood types related to the six genotypes?” page.
What are all of your possible genotypes, based on the blood type you listed above?
______________________________________________________________________________
What are your parent’s possible genotypes?___________________________________________
Click on the “Alleles Inherited” button to continue.
Read the “How are ABO alleles inherited by our children?” page carefully. Using the blood type
calculator, check to see if you were correct about the blood types of your parents. Now hook up
with another person and use the second calculator to see what the possible blood types of your
children would be. Write your blood types and your children’s possible types
here:__________________________________________________________________________
Now click on the “Rh Factor” button to continue.
Carefully study the page “What about the Rh factor?” then click on the “Blood Types Problem
Set” to test what you’ve learned.
Once there, click on the “Begin Problem Set” to test your group. There are only six problems, so
be careful! Be sure to read the explanations both when you are right and when you are wrong…
Record your score here: _____correct out of six.

Please note that you now have 2 WINDOWS OPEN. If you look at the bottom of your
computer, you will see that you can still access my web page by clicking on the
minimized window. Read through the web page very carefully. If you need to, you
may print out the text and read it that way or just re-read as often as necessary.

performed?_________________
2)What year were platelets discovered? ______________ 3) By
whom?_______________________
4) What scientist was able to perform the first transfusion using crossmatching, and over the next
several years successfully used the procedure in 128
cases?_______________________________________
5) In what year was the first blood depot established and why was it
established?_________________

Next, click on this link to learn all about the blood groups:
http://www.pbs.org/wnet/redgold/basics/bloodgroups.html
ABO blood groups are defined by specific, inherited molecules known as 6)
______________________
that are found oon the surface of 7) ____________ blood cells.
A person has a natural immunity or antibody to protect themselves from other blood types.
8) What antibody(ies) does a person with blood type O
have?_________________________________
9-10) List the most common blood types in the United States. _______ and _______.
11) In the U.S., what is the percentage of peoople with type AB-?_________________________.
