  14. CREATE YOUR OWN PEDIGREE • Think of a trait that some (but not all) of your family members carry. • Some examples may be: • Left-Handedness • Curly Hair • Tongue Rolling • Widow’s Peak • Attached Earlobes • Freckles • Allegies • Cleft Chin • …….

  15. SECOND STEP… • Begin By Drawing your family members, using a • CIRCLE—Women/girls • SQUARE—Men/Boys • DO NOT SHADE ANYTHING AT THIS POINT Here is a diagram to help you remember how to draw one:

  16. THIRD STEP • If anyone is deceased, Make a diagonal slash mark through their circle or square. • Then use a Marker to Color in any family member with the trait. • If you do not know the trait for sure, you can take it home and complete it over the weekend.

  17. FOURTH STEP • Label your pedigree with your name, your family name • Place a “key” at the bottom or side indicating what each shape means.
