Pedigree Chart Information
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.

Example of a pedigree chart using Ahnentafel numberingIn 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.
More visible, therefore, are the pedigrees recorded in published works, such as Burke's Peerage and Burke's Landed Gentry in the United Kingdom and, in continental Europe by the Almanach de Gotha.
In animal husbandry
In the practice of selective breeding of animals, particularly in animal fancy and livestock, including horses, pedigree charts are used to track the ancestry of animals and assist in the planning of suitable breeding programs to enhance desirable traits. Breed registries are formed and are dedicated to the accurate tracking of pedigrees and maintaining accurate records of birth, death and identifying characteristics of each registered animal.
