The Role of Reference DNA Testing in Forensic Genetic Genealogy
Reference DNA testing is key to accelerating and improving forensic genetic genealogy, but it only works if we protect donor privacy and use rigorous science that will hold up in court.

The GEDCOM format is the foundation for a graph-based map of human relationships that, when combined with DNA and metadata, will power automated, AI-driven identity resolution.
We need to strengthen four pillars of FGG—ultra-sensitive DNA profiles, enhanced search capabilities, automated database tools, and public participation—to realize the full potential and truly democratize this technology.
While autosomal SNP markers are central to forensic genetic genealogy, mtDNA and Y-DNA markers offer valuable lineage-specific insights, at no additional cost, that enhance and accelerate forensic investigations.
Familial search (FS) and forensic genetic genealogy (FGG) both use kinship relationships to generate investigative leads but differ significantly in scope and application.
In forensics, imputation should be used sparingly (if at all) and applied only where data quality and density allow for reliable analysis. Nothing replaces the value of high-quality, directly observed DNA data.
