Three-Generation Pedigree
A classic three-generation classroom pedigree. Grandparents are at the top, their children in the middle row, and grandchildren at the bottom. The proband (the person whose trait history is being studied) is marked with the standard arrow and labeled P. The affected grandfather shows that a trait can enter the chart from the older generation.
