Oompa Loompa Genetics
 Read & answer each question in the space provided
 Use a Punnett Square to solve any necessary problems
1. Oompas generally have ORANGE faces which are caused by a dominant gene. The
recessive condition results in a BLUE face. Develop a KEY to show ALL the possible
genotypes & phenotypes for the Oompas' face colors.
 O = orange gene (face color)
 o = blue gene (face color)
Genotype
Phenotype
2. Two heterozygous Oompas are crossed. What is the probability that the offspring will
have orange faces? _____ x _____
Probability of orange face ________
3. An orange-faced Oompa (homozygous) is married to a blue-faced Oompa. They have 8
Oompa children. How many of these children will most likely have orange faces? How
many will most likely have blue faces? _____ x _____
Number of orange-faced children ________
Number of blue-faced children ________
4. Otis Oompa has a blue face and is married to Ona Oompa who has an orange face.
They have 60 Oompa children. 26 of these children have blue faces. What are Otis &
Ona Oompa’s genotypes?
Otis Oompa’s genotype ________
Ona Oompa’s genotype ________
5. Odie Oompa has an orange face. In fact, everyone in Odie’s family likes to brag that
they are of a “pure” line. Odie marries Ondi Oompa who is heterozygous for face
color. Will anyone in Odie's family have to worry about them having children with blue
faces? Explain. _____ x _____
Does family have to worry... Yes or No? _____
Why or why not? __________________________________________________
6. Orville Oompa is heterozygous for face color and so is his wife Olga. They have 200
little Oompas. _____ x _____
Approximately, how many of the 200 Oompa children are
--- Homozygous orange? _____ (Do NOT give a % here; Give a real #)
--- Heterozygous orange? _____
--- Homozygous blue? _____
7. Oompas can have blue, yellow, or green hair (with green being the most common). The
green phenotype results from having 2 DIFFERENT genes (alleles) for hair color. This
condition is known as incomplete dominance. Develop a KEY to show ALL the possible
genotypes & phenotypes for the Oompas' hair colors. Hint: Yellow & Blue make Green.
Genotype
Phenotype
8. Oscar Oompa recently married Olivia Oompa. Oscar has the traditional green hair
while Olivia has yellow hair. Oscar really wants ALL of their kids to have green hair
like him. Will he get his wish? Explain. _____ x _____
Will Oscar get his wish... Yes or No? _____
Why or why not? __________________________________________________
9. Olivia Oompa (from question #8) eventually learns that Oscar has been cheating on
her. She files for divorce and gets full custody of their 2 yellow-haired children. To
get back at Oscar for cheating, she marries Ozzie Oompa (who has blue hair) and the
two end up with 138 Oompa children! Why will this anger Oscar so much?
_____ x _____
Why will Oscar be so upset? _________________________________________
10. When Willy Wonka rescued the Oompa Loompas from Loompaland a long time ago, he
came to learn they all have a form of short-limbed dwarfism known as achondroplasia.
Achondroplasia is inherited in an autosomal dominant pattern. Willy Wonka
(homozygous recessive for the condition) eventually fell in love with Olga Oompa
(heterozygous) and the two are planning on having children in the near future.
Is there any chance they can have children WITHOUT achondroplasia? Explain.
_____ x _____
Any chance of children WITHOUT achondroplasia... Yes or No? _____
Why or why not? ________________________________________
