Genetics Project
This project compliments what you are learning in Chapter 3 Genetics.
Genetics: The Science of Heredity
These boxer puppies and their mother resemble each other in many ways. However, there are also noticeable differences between one dog and the next.
Chapter 3 Project:
Did you ever wonder why some offspring resemble their parents while others do not? In this chapter, you'll learn how offspring come to have traits similar to those of their parents. In this project, you'll create a family of "paper pets" to explore how traits pass from parents to offspring.

Your Goal
To create a "paper pet" that will be crossed with a pet belonging to a classmate, and to determine what traits the offspring will have.

To complete this project successfully, you must
create your own unique paper pet with six different traits
cross your pet with another pet to produce six offspring
determine what traits the offspring will have, and explain how they came to have those traits

Get Started
Team with a classmate to determine which of you will have the Male or Female pet.
Cut out your pet from either blue or yellow construction paper. You may select two traits of your choice, then include the other traits listed below for your pet:
skin color will be either the "yellow" or "blue" colored paper.
square eyes or round eyes;
oval nose or triangular nose;
pointed teeth or square teeth.
Then create your pet using materials of your choice.
Suppose the two pets were crossed and produced six offspring. For each trait, use coin tosses to determine which allele the offspring will inherit  from each parent. Construct a paper pet for each offspring, showing the traits each one has inherited. Write the genotype for each trait on their backs.

When constructing your paper pet:
On the back, write what alleles your pet has for each trait. Use XX for a female, and XY for a male. The dominant alleles for the other four traits are: B (blue skin), R (round eyes), T (triangular nose), and P (pointed teeth). (Hint: If your pet has a trait controlled by a dominant allele, you can choose which of the possible combinations of alleles your pet has.)

With your partner, plan a display of your pet’s family. Label the parents the P generation. Label the offspring the F1 generation. Construct a Punnett square for each trait to help explain the inheritance pattern in your pet’s family. (Hint: Attach your pets to the display in a way that lets viewers turn the pets over to read their genotypes.)

Present Your Pets
On October 28th you and your partner will display / present your pet's family and analyze the inheritance patterns.
How you display / present your pets is up to you. Remember Homo Faber!
Present Your Project
Finalize your display of your pet’s family. Be prepared to discuss the inheritance patterns in your pet’s family. Examine your classmates’  exhibits, and see which offspring look most like, and least like, their parents. Can you find any offspring that “break the laws” of inheritance?

Check Your Progress
You'll be working on this project as you study this chapter. To keep your project on track, look at the Section Reviews below.

Click a section below and answer the questions and review the concepts. The essay questions are more for your review. I do not expect your answers to look like the one displayed in the essay review answer section, but you should know the basic concepts.

Reflect and Record
How did your paper pets help you learn about genetics?
How do the inheritance patterns in your pet’s family resemble real-life patterns?
How could you use paper pets to help you understand other topics in genetics?
