# Consumer Ancestry Testing **Domain:** Genomics / Consumer Platforms / Identity **Doc Type:** Canonical Technology Node **Maturity:** Developed ## Definition **Consumer ancestry testing** uses selected genetic markers and proprietary reference datasets to estimate biological relationships, population affinities or lineage assignments for customers. ## Evidence Boundary Results are probabilistic and provider-dependent. Reference panels, category definitions and algorithms change; percentages are not direct measurements of culture or identity. Mitochondrial and Y-chromosome haplogroups represent narrow lineage paths rather than a complete family tree. [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] places these products downstream of molecular clocks, population genetics and computational phylogeny. The consumer interface can hide the institutional choices that turn sequence into narrative. ## Continuity and Rights Genetic data is durable, relational and difficult to revoke because one person's sample reveals information about relatives. Custody therefore implicates consent, secondary use, law-enforcement access, deletion and model retraining. ## Key Insight **An ancestry result is a model-mediated claim about descent, not a complete biological identity and never a proof of personal continuity.** ## Sources / Provenance - Federal Trade Commission consumer guidance on DNA testing: https://consumer.ftc.gov/consumer-alerts/2017/12/dna-test-kits-consider-privacy-when-you-add-cart - National Human Genome Research Institute: https://www.genome.gov/ ## See Also [[wiki/Haplogroup|Haplogroup]], [[wiki/Population Genetics|Population Genetics]], [[wiki/Genetic Privacy|Genetic Privacy]], [[wiki/Reconstructed Person|Reconstructed Person]]
