16
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.

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