Mrs. Price’s genetics
webquest
Introduction – Genetics control what the offspring is
going to look like. Two people are going to get
married, they will become Mr. and Mrs. Smith. One
has blue eyes and the other has brown eyes. They
want to know what color of eyes their children will
have. You need to research to find out what the
chances are that their children will have blue eyes.
Task – You need to research who Gregor Mendel
was. You also need to research dominant and
recessive traits and the terms phenotype and
genotype using the Internet. You need to create as
many punnett squares necessary to figure out what
the chances are that Mr. And Mrs. Smith’s children
will have blue eyes. You will also create your own
activity to do with the class dealing with any
dominant and recessive trait.

Research on the sites above or others to find the definitions
of the vocabulary words: recessive, dominant, phenotype,
genotype, punnett square, and find out who Gregor Mendel
was and what he is well known for.
Look at some other traits besides eye color on the sites and
become familiar with which trait is dominant and which one
is recessive.
Become familiar with knowing how a recessive trait will
show as a phenotype.
Become familiar with knowing how a dominant trait will
show as a phenotype.
Go through the process of the practice punnett squares on
http://www.athro.com/evo/gen/punexam.html Print out
when finished.
Actually draw your own punnett squares to figure out the
chances that Mr. and Mrs. Smith’s children will have blue
eyes. Give your answer in a percent.
Come up with an activity on your own to do with the rest of
your class to practice punnett squares. This could be an
activity that you find on the Internet.
OUTCOME - I expect the information that you collect
to be turned in completed. I would like it in some type of
folder, and label each section as follows: VOCABULARY,
OTHER TRAITS (telling which is dominant and which is
recessive), PRACTICE PUNNETT SQUARES (print this
out when completed and put in folder), MR. AND MRS.
SMITH (punnett squares and answers in percents should be
included), INDIVIDUAL ACTIVITY (If found on the
Internet, please give me the resource where you found it.)
CONCLUSION- When finished, you should be able to
tell me who Gregor Mendel was, and describe how a
dominant and recessive trait would show up in an offspring.
You should also be confident in the genetic terminology we
will using in class.
