genetic genealogy
Hereditary family tracing
Genetic genealogy uses DNA testing to establish family relationships and ancestry.
Traditional genealogy relies on documents—birth certificates, census records, immigration logs—while genetic genealogy examines inherited markers to confirm lineage, identify unknown relatives, or trace ethnic origins.
The field has expanded dramatically with consumer testing services: She discovered a half-sibling through genetic genealogy.
Law enforcement increasingly uses genetic genealogy to identify suspects by matching crime-scene DNA to relatives in public databases.
