Congratulations!Congratulations!

Projects

2. Locate and read different descriptions of the Punnett
   Square on the Internet. Find four different scenarios that
   can be represented using a Punnett Square. Print these
   four scenarios and then explain how the Punnett Square
   represents them.


3. Get ConnectED Create sample genes for pet traits. Go to
   connectED.mcgraw-hill.com/ to get the recording sheet
   for the information you will create. Complete the table for
   4 different pets and the possible characteristics of each pet.
   Write 1–2 paragraphs describing how the Punnett Square
   is used in genetics and how math is involved with the Punnett Square.


4. Create a poster board containing information about the data you have
   gathered about genetics and pet traits. Include a table displaying your data.

Making the Connection

Use the information collected about genetics as needed to help in

these investigations.

Language Arts

Research the theories of genetics. Write an essay that explains how genes

work and what it means for a trait to be dominant or recessive.

Science

Explain how a Punnett Square can be used to determine the probability of

inheriting certain features from parents.

Health

Select a health condition or disease and research how genetics may play

a part in the disease. Write 1–2 paragraphs explaining how genetics may

infl uence someone’s risk of getting the disease and steps that can be taken

to reduce the risk factors.

• You can use a computer projector
  to share your completed pet traits
  table with the class.


• Instead of a poster board, you can
  create a PowerPoint® presentation
  to display and share the
  information from your project.

Great work! Did you find out some interesting things about

pet traits? We hope you enjoyed your experience in the

amazing world of genetics and saw the large role mathematics

plays in understanding this world.
