The drawing

What a genetic pedigree is.

A genetic pedigree is a family diagram that uses standardized symbols to show biological relationships and genetic status across generations. It can identify affected relatives, known carriers, unaffected relatives and the proband, the person whose history prompted the chart.

A pedigree summarizes a family history; it does not diagnose a condition. Clinical interpretation, testing and care decisions need review by an appropriately qualified professional.
