What we do
Forensic Array: Single Source
We analyze and match single source DNA samples to our extensive database.
The forensic microarray can be used with DNA extracted from sample sources such as blood, saliva, semen and tissue (non-FFPE). Using our customized Screening Array to generate a single nucleotide polymorphism (SNP) profile for use in Investigative Genetic Genealogy (IGG).
Once a data file is generated it is matched to FamilyTreeDNA (FTDNA) and GEDmatch for IGG and familial matching at no additional charge.
Forensic Array: Mixed Source
We analyze and match mixed source DNA samples to our extensive database.
It may be possible to run a forensic array on a mixed source DNA sample if a reference sample can be provided. Using two sources, it's possible to reconstruct a SNP profile of the second DNA source.
Mixed source samples are evaluated on a case by case basis to determine the chance of success. Pricing includes upload to both the FTDNA and GEDmatch databases.
Forensic Array File Reformat
We match raw DNA to our extensive database.
Raw data files not generated by Gene By Gene or created by methods other than microarrays can be reviewed, re-analyzed, and re-formatted so that they are compatible with the FamilyTreeDNA database.
Includes raw data SNP profile, FTDNA account creation, and upload to the FTDNA database for matching.
Forensic Genome Sequencing
We can use our sequencing techniques to extract low quantities or poor quality DNA to then match to our extensive database.
Samples that are not candidates for the forensic array due to low quantities or poor quality may be analyzed using whole genome sequencing.
Gene By Gene will process the sample and provide a SNP profile that will be uploaded to FTDNA and GEDmatch at no additional charge.
Y-111 DNA Testing
We can identify males through our Y-chromosome testing to then match to our extensive database.
The Y-111 DNA tests 111 STRs (Short Tandem Repeats) markers and looks for matching markers or "STRs" between two men. This allows for investigation into the male’s paternal line by helping to identify potential surnames, Y-DNA relatives, and a Y-DNA haplogroup.
Genealogical Research and Family Tree Building
Review familial matches & construct family trees.
A team of highly specialized genealogists will provide expertise in reviewing familial matches and constructing family trees to help identify deceased individuals and/or suspects.
Reference Testing
Confirm relationships using the Forensic Array.
Reference testing is used to test potential family members of individuals identified using the Forensic Array to confirm relationships. Informed consent from the tester is required.
