Unit 7: Mr. Potato Head Genetics

Data Sheet 2

Directions: Choose a partner. Decide who will be the “daddy” and who will be the “mommy.” Mate and produce two children. Circle the allele being passed on and then write the genotype and phenotype for the trait.

Child #1 name ______

Trait / Dad’s Alleles / Mom’s Alleles / Offspring
Genotype / Offspring
Phenotype
Shoe color – Blue (A) is dominant to all other colors (a) / A a / A a
Eye color – Black (B) is dominant to all other colors (b) / B b / B b
Nose color – Orange (D) is dominant to all other colors (d) / D d / D d
Ear – Pierced (E) is dominant to unpierced (e) / E e / E e
Arm color – White (F) is dominant to all other colors (f) / F f / F f
Mouth color – Red (G) is co- dominant with white (G1) / G G1 / G G1
Blood Type- IAIA or IAi= type A
IBIB or IBi = type B; IAIB = Type AB; ii = Type O / IB i / IA i
Intelligence –
7-8 dominants = genius (wears glasses)
2-6 dominants = normal intelligence
0-1 dominants = Very slow (wears hat) / H h J j K k L l / H h J j K k L l
Sex – Boys have mustaches; Girls have purses / X Y / X X

Questions

  1. What percentage of the child’s genotype does each parent contribute?
  1. Why did you need a random process to determine which trait to pass on? What event did that simulate?
  1. Use examples from the activity to explain your understanding of the following inheritance patterns:
  2. Dominant
  3. Recessive
  4. Incomplete Dominance
  5. Polygenic
  6. Multiple Allele
  7. Create a Punnett square for ear piercing. What was the chance that your offspring would have pierced ears? How does the class data compare to the predicted data (from the Punnett square)? Why is it different (if it is different)?
  1. Create a Punnett square for mouth color. What was the chance that your offspring would have a pink mouth? How does the class data compare to the predicted data?

Questions:

  1. Compare your potato head family to the others in the class. Do you notice similarities/differences?
  1. After playing “survivor,” explain how evolution and genetics are connected.
