Pedigree Chart

A pedigree chart is a diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next,[1][2][3] most commonly humans, show dogs, and race horses. The word pedigree is a corruption of the French "pied de grue" or crane's foot, because the typical lines and split lines (each split leading to different offspring of the one parent line) resemble the thin leg and foot of a crane.In England and Wales pedigrees are officially recorded in the College of Arms, which has records going back to the Middle Ages, including pedigrees collected during roving inquiries by its heralds during the sixteenth and seventeenth centuries. The purpose of these heraldic visitations was to register and regulate the use of coats of arms. Those who claimed the right to bear arms had to provide proof either of a grant of arms to them by the College, or of descent from an ancestor entitled to arms. It was for this reason that pedigrees were recorded by the visitations. Pedigrees continue to be registered at the College of Arms and kept up to date on a voluntary basis but they are not accessible to the general public without payment of a fee.
