GENETIC: Family Pedigree Instructions

Build a diagram of your family, using proper pedigree symbols. Indicate where you are on the pedigree.
Select one trait from the list below to find one where there are different phenotypes in at least two people in the family.**
Color or shade the pedigree to show the phenotypes for all people. Place a ? for each person on the tree that you were not able to test.
Research (using a reliable source, does not need to be primary or secondary) whether this trait is dominant, recessive, incomplete, or codominant) and cite
your sources.
List the genotype(s) clearly for all individuals in the pedigree. Assume that the trait is not sex-linked unless you know otherwise.
Predict the probability of one couple on your pedigree having a child of a particular genotype. Make a Punnett Square to show the probability.
