Forensic Genetic Genealogy

What is forensic genetic genealogy?

Forensic genetic genealogy (FGG) is an investigative technique that combines advanced DNA analysis with genealogical research to generate leads in criminal cases. Before the genealogical research can begin, a DNA profile must be developed using single nucleotide polymorphism (SNP) testing or whole genome sequencing (WGS)—methods that generate hundreds of thousands of genetic markers.

Once a suitable SNP profile is generated, experienced and board-certified genealogists use it to research ancestry and build family trees to develop investigative leads. DNA analysis from a person of interest is then used to determine if the individual is a match.

Does Sorenson Forensics offer FGG?

Sorenson Forensics was acquired by Othram in September 2026 and now through Othram, Sorenson customers now have access to FGG technology if their case has not been solved through traditional forensic DNA testing. Read the announcement.

How effective is FGG?

FGG has proven to be an effective tool in helping generate investigative leads in unresolved cases, especially when traditional investigative methods have not provided answers. FGG has helped identify unknown suspects, assist with unidentified human remains cases and move cold cases forward. See Othram’s success stories for real-world examples.
