Question

What symbol represents the death of an individual in a pedigree chart?

Options

• An upside-down symbol

• An X mark inside the symbol

• A diagonal line through the symbol

Answer 1

Death of an individual is represented by a diagonal line drawn through the symbol (square, circle, or diamond) in a pedigree chart. This notation allows the pedigree to include deceased family members whose genetic information may still be relevant to inheritance analysis.
