- A pedigree is a diagram that depicts the biological relationships between an organism and its ancestors. It comes from the French “pied de grue” (“crane’s foot”) because the branches and lines of a pedigree resemble a thin crane’s leg with its branching toes. A pedigree is used for different animals, such as humans, dogs, and horses.

By analyzing a pedigree, we can determine genotypes, identify phenotypes, and predict how a trait will be passed on in the future. The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant , recessive , autosomal , or sex-linked .
Pedigrees are a useful method to model the inheritance patterns of traits within families. By using symbols and analyzing phenotypes, we can infer genotypes and understand the role of autosomal dominant traits.

May 23, 2024 · A pedigree, as related to genetics, is a chart that diagrams the inheritance of a trait or health condition through generations of a family. The pedigree particularly shows the relationships among family members and, when the information is available, indicates which individuals have a trait (s) of interest.
Pedigree, a record of ancestry or purity of breed. Studbooks and herdbooks, which contain pedigrees for different types of animals, are maintained by record associations or breed organizations in many countries. In human genetics, pedigree diagrams are used to trace the inheritance of a specific trait or disease.

The information from a pedigree makes it possible to determine how certain alleles are inherited: whether they are dominant , recessive , autosomal , or sex-linked .
Pedigrees are diagrams that show the phenotypes and/or genotypes for a particular organism and its ancestors. While commonly used in human families to track genetic diseases, they can be used for any species and any inherited trait.
