Making Paper Pets

 

Goal:  Create punnett squares to show an organism’s genotype and phenotype.  Use probability such as coin tosses to predict the results of genetic crosses.

 

Background:  You will create imaginary parent paper pets.  They will have six offspring.  You need to determine their appearance and genetic make-up by creating punnett squares.  This assignment combines your knowledge of phenotype, genotype, punnett squares, and probability.  It is worth 60 pts (45% of your 2nd quarter grade).  Each person will be graded individually based on his/her work.

 

Procedure: 

Day 1:

Partner #1’s job:

  1. Sign your name below
  2. Decide what traits you want to have (see the attached chart).
  3. Write your traits in the phenotype and genotype column.  Your gender should be XY if you are male. Your gender should be XX if you are female. 
  4. Cut out the blue or yellow paper to fit onto the parent pet.
  5. Paste the chart of phenotypes and genotypes on the back of the parent pet.
  6. Draw your 4 traits on the front of your parent pet (see the attached chart).
  7. Write your first and last name on the big parent pet; not a made-up name.
  8. Decorate your parent pet with construction paper.
  9. Put your pets in the envelope.  Write your names on the envelope.  Place them in the shelf that belongs to your class period.

 

Partner #2’s job:

1.  Sign your name below

2.  Decide what traits you want to have (see the attached chart).

3.  Write your traits in the phenotype and genotype column.  Your gender should be XY if you are male. Your gender should be XX if you are female. 

4.  Cut out the blue or yellow paper to fit onto the parent pet.

5.  Paste the chart of phenotypes and genotypes on the back of the parent pet.

6.  Draw your 4 traits on the front of your parent pet (see the attached chart).

7.   Write your first and last name on the big parent pet; not a made-up name.

8.  Decorate your parent pet with construction paper.

9.  Put your pets in the envelope.  Write your names on the envelope.  Place them in the shelf that belongs to your class period.

 

Day 2:

Partner #1’s job

1.  The male partner should toss a coin to find out if you’re having a boy or a girl since the father determines the sex of the offspring.  Heads= boy, tails= girl.  You will be having six offspring, so flip six times.  The sex of the baby has nothing to do with the body color!!

2. Create two punnett squares to find out the genotypes and phenotypes for body color and teeth of your kids. Write the punnett squares below.

3. Write the offspring's traits in the phenotype and genotype column in the offspring pets.

4.  Paste the chart of phenotypes and genotypes on the back of 3 offspring pets.

5.  Draw the offspring’s traits.

6.  Name your offspring with your partner.

 

Partner #2’s job

1.  The male partner should toss a coin to find out if you’re having a boy or a girl since the father determines the sex of the offspring.  Heads= boy, tails= girl.  You will be having six offspring, so flip six times.  The sex of the baby has nothing to do with the body color!!

2. Create two punnett squares to find out the genotypes and phenotypes for the nose and eye shape.  Write the punnett square below.

3. Write the offspring's traits in the phenotype and genotype column in the offspring pets.

4.  Paste the chart of phenotypes and genotypes on the back of 3 offspring pets.

5.  Draw the offspring’s traits.

6.  Name your offspring with your partner.

 

 

 

 

 

 

 

 

                       

 

 

 

 

 

 

                                                           

Day 3:

Both Partners

  1. Cut/Paste the decorations for your offspring and parent pet.  Each parent can decorate 3 kids.

Day 4:

Both Partners

  1. Finish cutting/pasting the decorations for your offspring.

 

  1. Write the punnett squares for the four traits (body color, eyes, nose, teeth) and the probability (ex: 100% blue) for each trait. 

 

3. Name your family with your partner. It must be an appropriate name. (Ex:  The Brady Bunch).

Rubric:

Completing genotype & phenotype parent chart= 10 pts.

Completing 3 genotype & phenotype offspring charts=30 pts.

Decorating parent= 3 pts.

Decorating offspring= 3 pts.

Writing the punnett squares= 12 pts.

Name of appropriate family name= 2 pts.

 

I understand how to do my job.  I will do my job and not take over my partner’s job, even if he/she is absent.  I will be positive and respectful when working on this assignment.  I will carry out my jobs and will not give the excuse, “my partner wouldn’t let me do my job”.  I will use my time wisely.
