Question: Who is the “father” of genetics?
______

SHOW ALL WORK and PUNNET SQUARES Name:______

1. Oompahs generally have blue faces which are caused by a dominant gene. The recessive condition results in an orange face. Develop a "key" to show the genotypes and phenotypes possible for Oompa Loompas.

Genotype / Phenotype


2. Two heterozygous Oompahs are crossed. What is the ratio of orange faces to blue faces?


Ratio: ______

3. A blue faced Oompah (homozygous) is married to an orange faced Oompah. They have 8 children. How many children will have blue faces?
Blue face genotype ______
Orange face genotype ______
4. Otis Oompah has an orange face and is married to Ona Oompah who has a blue face. They have 60 children, 30 of them have orange faces. What are the genotypes of the parents.
Otis Oompah’s genotype ______Ona Oompah’s genotype ______

5. Odie Oompah has a blue face. In fact, everyone in Odie's family has a blue face, and the family boasts that it is a "pure" line. (They do not carry the recessive allele.) Much to his family's horror, he married Ondi Oompah who "gasp" has an orange face. What are the gentoypes of their children? Is Odie's line still "pure"?

6. Ona Oompah (from#4) divorces Otis and marries Otto. Otto has an orange face. What is the probability that Ona and Otto's children will have orange faces?
Ona Oompah’s genotype _____
Otto Oompah’s genotype _____

7. Orville Oompah is blue faced (heterozygous) and his wife, Olga Oompah, is blue faced (heterozygous). They have 200 children. How many of them are the following:
Blue faced (homozygous):______Blue faced (heterozygous): ______
Orange faced (homozygous): ______Orange faced (heterozygous): ______

8. Oompah Loompah’s have green, red, or purple hair. Red is the dominant trait. However, the heterozygous genotype shows up as purple. Make a “key” to show genotypes and phenotypes of possible hair colors.

Genotype / Phenotype

9. A homozygous red head and heterozygous purple head are crossed. Use a punnet square to show the possible genotypes and phenotypes.


10. Olivia Oompah is married to Odo Oompah and they both have purple hair. They have 500 children. (Yikes!) How many of those Oompah’s have each color of hair?


Red hair ______Purple hair ______Green hair ______
11. In the land of Oompah, green hair is highly valued. Green haired Oompahs even get special benefits. Oscar Oompah has purple hair but he wants to find a wife that will give him green haired children. What color hair should his wife have? What would be his second choice?
12. On a separate sheet of paper (stapled to this sheet), write a story about two Oompah Loompa’s starting a family. Mention the genotypes and phenotypes of these two Oompah’s, and how their traits (face color, and hair color) have been passed down to their children. Be creative but appropriate. Use punnet squares to show how their children inherited their traits.

Hint to Getting Started:

#1:


Oompah Loompas generally have blue faces which is caused by a dominant gene. The recessive condition results in an orange face. Develop a "key" to show the genotypes and phenotypes possible for Oompa Loompas.
B = blue face
b = orange face
possible genotypes (with phenotypes) would be:
Key:
BB (blue faced)
Bb (blue faced)
bb (orange faced)
