Where did that trait come from?”

Choose at least one human genetic trait – dominant or recessive, but not one that is controlled by multiple alleles (hair color, skin color…) observable in your family. Use the internet to find out as much information about the trait as you can. Interview as many of your family members as possible from as many generations as possible and take notes about how a specific trait has been inherited in your family. You may wish to collect photographs (or photocopies of photographs, since you should not damage those that may be family heirlooms) to use in your report. After you have collected your notes, construct a pedigree or family tree of the trait in your family members. You will make a short oral report and turn in your project notes, data, and pedigrees/trees.

You will have 10 Days to collect your data from family members, make a family tree (pedigree) showing the trait being passed on from relative to relative, and write a 1-2 paragraph summary of your findings. (If you only know one side of your family you will just use the side of your family you are familiar with. If you do not have access to any of your birth relatives you may use the family you are living with and look at traits that are passed along in their family.)

Your project should include: a family tree (aim for at least 5 people and 3 generations if possible), pictures (your picture is needed even if you are unable to get other photos of family members), you must have a key to show the trait you have chosen and whether it is dominant or recessive, the allele pairs for that gene and what they mean, and for each individual in your family tree you must tell the trait that they show as well as show the gene pair you believe that they have.

Have fun with this project! I look forward to seeing what makes each one of you special!

The following is a survey of traits for you to look through to help you decide what trait you would like to look at in your family. Keep in mind, DO NOT USE a trait that no one in your family shows, or one that everyone in your family shows, there needs to be diversity!
