Instructions:  Get with a partner and determine your phenotype for each of the traits listed below.  Identify as much of your genotype as you accurately can.

Homework:  Determine the phenotype and genotype of your parents.  (If you do not have access to one or both of your parents, determine the phenotype and genotype of your sibblings.)   When you have completed identifying your parent's traits, see if you can further determine your own genotype.  Pick one trait and draw a pedegree chart as completely as you can.
