Parents
Kids
7. Processing Page:
• Draw a pedigree of a family that has a mom, a
dad, and 3 kids: 2 boys and 1 girl.
• Now add grandparents: draw the dad’s
parents on the pedigree.
8. How do we represent traits?
= Dominant trait
= Recessive trait
9. Processing Piece:
• Look at the pedigree you drew before. Show
that the grandfather has albinism (a recessive
trait.)
• Show that the little girl also has albinism.
11. Processing Piece:
• Look at your pedigree. How many generations
are there?
• Label them I, II, III, etc.
