1 line of descent; lineage; ancestry.
2 a chart that shows the genetic makeup of a person's ancestors, used in the mendelian analysis of an inherited characteristic or disease in a particular family. It typically uses squares to represent males and circles to represent females. The figures may be unshaded, shaded, or partially shaded to designate normal individuals, those affected by the disease or trait, and those who are carriers. The generations are numbered with roman numerals at the left, with the most recent at the bottom, and members within each generation are designated by arabic numerals from left to right according to age, with the oldest at the left. The inquiry begins with the siblings of the affected person and proceeds to the parents and grandparents and any of their immediate relatives. See also Punnett square.
Academia A popular term for a person’s educational ‘lineage’—i.e., where he or she studied; a physician with a pedigree has studied at ‘premier’ undergraduate institutions, medical schools, and ‘center of excellence’ teaching hospitals
Genetics An ancestral chart of the blood relatives and mates of an index patient with a disease or a particular hereditary trait; a family health history diagrammed with a standard set of symbols to indicate the individuals in the family, their relationships to one another, and members with a particular disease

pedigree 

A chart or diagram of the ancestral history of a family or of an extended family (kindred), or of individual family members, their relationships and their status regarding a trait or condition. It is used in genetics to analyze inheritance. The analysis often begins with an affected family member (called a proband or propositus) through whom the family is ascertained (Fig. P5). See gene; inheritance.

pedigree

a table, chart, diagram, or list of an animal's ancestors, used in genetics in the analysis of mendelian inheritance, and in the prediction of productivity and breed quality in the offspring.

pedigree analysis
a useful basis for planning a program to eliminate an inherited defect; the analysis determines the probability that each prospective parent is homozygous for the normal gene, i.e. is not a carrier for the anomaly gene; potential parents with a probability of >95% can be used with confidence.
pedigree herds
herds or flocks composed of animals whose pedigrees are known. Not necessarily stud herds or registered herd but the terms are usually synonymous.
pedigree index
the average of the predicted difference of the sire and the cow index of the dam. The pedigree index is allotted to the offspring.
pedigree selection
use of an individual's pedigree to select breeding animals.
pedigree verification
verification via breed societies and production testing agencies, horse stud books and race records are all used; checks via coat color, blood cell antigens may assist.
