In order to accurately depict this information, various symbols are used in pedigree charts to represent different relationships and characteristics within a family tree. Understanding these symbols is key to interpreting and creating pedigree charts effectively.

A filled-in shape typically indicates a person affected by a certain condition or disease, while an empty shape represents an unaffected individual.
