01
Sample record first
Identity work starts with cultivar name, source notes, aliases, plant type, and handling metadata so the genetic result is tied to a reviewable record.
Methodology
How True Cut builds the Forensic Identity Dossier.
True Cut treats genetic identity as a documented workflow, not a single chart or name claim. The method combines clean sample intake, genome-wide marker comparison, relationship views, and a bounded Forensic Identity Dossier.
02
Genome-wide marker profile
The analysis uses marker data distributed across the genome to build a stable comparison profile for each submitted sample.
03
Pairwise similarity
Observed IBS values compare submitted samples and reference records directly, helping separate matches, close relationships, and clear differences.
04
Population context
PCA and branch views help users see genetic neighborhoods, but they are interpreted alongside pairwise similarity and sample metadata.
05
Forensic Identity Dossier
The Forensic Identity Dossier summarizes genetic similarity, relatedness, and identity evidence while avoiding unsupported claims about performance or ownership.
Data generation and QA
External marker data, internal review.
True Cut uses CD Genomics as an external sequencing and genotyping service provider for genome-wide SNP marker data. True Cut then applies its own analysis workflow, metadata review, and bounded interpretation before evidence becomes part of a Forensic Identity Dossier.
Quality controls
- Sample records are checked against submitted metadata.
- Analysis artifacts are regenerated from versioned inputs.
- PCA, IBS similarity, and relationship views are reviewed together.
- Public and dossier copy stays inside the approved claim boundary.
