CREATE YOUR OWN PEDIGREE

Begin By Drawing your family members, using a

CIRCLE—Women/girlsSQUARE—Men/BoysDO NOT SHADE ANYTHING AT THIS POINT

Here is a diagram to help you remember how to draw one:

SECOND 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.

THIRD STEP

Label your pedigree with your name, your family name

Place a “key” at the bottom or side indicating what each shape means.
