In a high school classroom setting, the sciences are emphasized. Through Biology, students are made aware of the things
around them and how things work and become what they are today. Fitting within this idea, where do the traits and
characteristics of people come from? How do we each come to look different from others around us? Why do we not always
look similar to our siblings?
To answer some of these questions, especially how we get our genes and the traits that express them, a Punnett square
can be a useful tool. In the search to answer questions about the study of genetics, the Punnett square needs to be
understood and used as a tool of discovery.
