The drawing

What a pedigree chart is.

A pedigree chart is a standard diagram used to trace a genetic trait through a family. Its shapes and fills show sex, relationships and whether each person is affected, unaffected or a carrier.

It is different from a general family tree because it records inheritance information across generations. A pedigree can help organize a family history for learning, research or a discussion with a qualified health professional.

FAQ

Common questions

What is a pedigree chart?

A pedigree chart uses standardized symbols to show family relationships and the inheritance of a genetic trait or condition across generations.

What do the symbols in a pedigree mean?

Squares and circles commonly represent male and female family members. Fills, hatching and labels can show affected, carrier, unaffected or other genetic status.

What is the difference between a pedigree and a family tree?

A family tree records ancestry and relationships. A pedigree adds standardized genetic status so a trait or condition can be traced through the family.

Can a pedigree show carrier status?

Yes. Describe which relatives are known or assumed carriers, affected or unaffected, and the chart can use the relevant pedigree notation.
