Lab C
Investigating Dominance in Human Traits
Directions: Use the information and data from the Lab Gummy Bear Genetics to perform this lab.
You have performed an activity that simulates cross-breeding experiments using gummy
bears. There are many other possible questions about genetics that you could investigate.
Design an observational study to investigate a human trait that shows simple Mendelian
dominance. Study the trait in the members of your family and then design a pedigree to
trace the trait. One example of a suitable trait is earlobe attachment. The gene for
unattached earlobes is dominant whereas the gene for attached earlobes is recessive. You
may also choose a different trait as long as it shows simple Mendelian dominance.
Please note that you must complete Lab B before beginning Lab C. Also, have your teacher
approve your design and safety precautions before beginning your experiment.
