A pedigree can be used to?

* Trace the inheritance of a particular trait through multiple generations of a family to determine the mode of inheritance and identify carriers.

* Assess risk of developing a genetic condition within a family and provide genetic counseling to help individuals make informed reproductive decisions.

* Identify the genetic basis of a disease and allow researchers to track its transmission and prevalence within a population.

* Study population genetics and evolutionary history by tracing the patterns of gene flow and genetic variation across generations.

* Build genetic databases and registries for research and clinical purposes, which can aid in the development of new treatments and therapies for genetic disorders.

* Establish relationships between individuals within a family, particularly in cases of paternity or maternity disputes, immigration cases, or adoption scenarios.
