Pedigree Project
1. Pick a genetic disease that we have discussed. Pick a letter to represent alleles.
2. Create an imaginary pedigree, at least 4 generations; each couple has 2 children
always and only.
3. The original couple are both heterozygous. Exceptions- Huntington’s’ and Taysachs
4. Use a coin to decide the genotype for each of the spouses throughout your
pedigree. H-heads, T-tails
HH-homozygous dominant, TT- homozygous recessive, HT- heterozygous
5. Create a punnett's square beside each couple to show the possible genotypes of
their offspring.
6. Use a coin to decide the genotype of their children.
7. Label the genotype of each individual, list both if two are possible.
8. Fill in the shapes of affected individuals, and half fill all carrier individuals.
9. Use roman numerals to number each generation and then number each individual
in the generation.
10. List the following information somewhere on your pedigree.
1. Who are the heterozygous individuals?
2. Who are the homozygous dominant individuals?
3. How many people in your pedigree have your disease? Who are they?
4. Using the rules above, could it have been possible to create a pedigree with
no homozygous recessive individuals?
11.Use the information on your disease in the book to write a description of your
disease and put it on or attached to your pedigree. What are the major differences
between a normal individual and an affected individual? You should include at
least 2 graphics, printed or drawn.
12.Write a fictional description for your pedigree. You may be as creative as you
want, but you must assign names, give a brief backstory for each couple including
how they met, and include a description of how the disease has affected the
family. Do affected individuals die early, live normal lives, require special
treatments, etc.
13.If you do a 3 minute presentation on your disease and pedigree you can earn 5
bonus points.
