Family Pedigree Project s1

Family Pedigree Project

Directions: Pick a disease or trait that runs in your family. It would be best to research and choose something that is known to be autosomal dominant, autosomal recessive, or X-linked recessive. Follow this trait or disease 3 generations. In other words, start with your grandparents, track it through to your parents’ generation, and finish off in your generation. You should only pick one side of your family to focus on, either your mother’s or your father’s. Be sure to adhere to the rules we learned in class (e.x. squares are males, colored in circles are affected females, Roman Numerals are used for generation number, etc.). Then compile a pedigree, tracking this trait or disease. If you prefer to make a digital copy instead, then please use Inspiration software to carry out the task. In addition to numbering all individuals in each generation, also include their first names on the pedigree. You must also compile a separate key outlining who each person is in every generation as well as whether or not they are affected. For instance, your key may look something like this:

Name: Teddi Brown Period: 1 Tracked: Red-green color blindness in my mom’s side of the family

Key: Generation I: 1. Laura – my grandmother; unaffected 2. Harry – my grandfather; affected

Generation II: 1. Sam – my uncle (Harry & Laura’s son); unaffected 2. Linda – mated with Sam; unaffected 3. Rachel – my aunt (Harry & Laura’s daughter); unaffected 4. Tom – mated with Rachel; unaffected 5. Gloria – my aunt (Harry & Laura’s daughter); unaffected 6. Martin – mated with Gloria; unaffected 7. Melanie – my mom (Harry & Laura’s daughter); unaffected 8. Landon – mated with Melanie (my dad); unaffected

Generation III: 1. Carl – my cousin (Sam & Linda’s son); unaffected 2. Dedra – Carl’s wife; unaffected 3. Cindy – my cousin (Sam & Linda’s daughter); unaffected 4. Ben – my cousin (Tom & Rachel’s son); affected 5. Bobby – my cousin (Tom & Rachel’s son); unaffected 6. Dillon – my cousin (Martin & Gloria’s son); affected 7. Courtney – my sister (Landon & Melanie’s daughter); unaffected 8. Me (Landon & Melanie’s daughter); unaffected Pedigree Project Grading Rubric
