(Wikipedia excerpt: ..."A pedigree chart is a diagram that shows the occurrence of certain traits through different generations of a family,[1][2] most commonly for humans, show dogs, and race horses.

The word pedigree is a corruption of the Anglo-Norman French pé de grue or "crane's foot", either 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[3] or because such a mark was used to denote succession in pedigree charts.[4]

A pedigree results in the presentation of family information in the form of an easily readable chart. It can be simply called a "family tree". Pedigrees use a standardized set of symbols, squares represent males and circles represent females. Pedigree construction is a family history, and details about an earlier generation may be uncertain as memories fade. If the sex of the person is unknown, a diamond is used. Someone with the phenotype (trait) in question is represented by a filled-in (darker) symbol. Heterozygotes, when identifiable, are indicated by a shaded dot inside a symbol or a half-filled symbol...")
