The Science

Cannabis identity,
defined from DNA.

True Cut uses genome-wide SNP fingerprinting and population-genetic analysis to document cultivar identity. It is not based on names, traits, or chemical profiles.

Research foundation

Built from cannabis genetics research.

The software is based on Dr. Anna Schwabe's dissertation research on variation in Cannabis sativa and her later peer-reviewed work on strain reliability, sample comparison, and genetic verification frameworks.

That foundation matters because True Cut is not asking users to trust a strain name or a marketing claim. The site connects the product workflow to the research problem: cannabis names, traits, and chemistry can drift away from measured genetic identity.

WHAT THIS IS

Identity is the foundation.

True Cut draws a bright line between identity documentation and other genetic or legal uses.

What it is

  • Genetic identity verification
  • Cultivar documentation
  • Relationship analysis

What it is not

  • Chemical testing
  • Trait prediction
  • Breeding optimization
  • A grant of legal ownership
Markers explained

What is a genetic fingerprint?

A genetic fingerprint is a pattern across many positions in the genome. Each position is a marker, and the combined pattern helps distinguish one genotype from another.

Unlike cannabinoid or terpene profiles, the DNA pattern does not shift with light, nutrients, harvest timing, or processing. That stability is why marker data can anchor identity.

The fingerprint does not decide historical naming or legal ownership by itself. It documents whether samples are identical, different, or related.

Sample A matches the expected marker pattern at the highlighted positions. Sample B differs at one marker. The real comparison uses many markers, not this simplified view.

POPULATION CONTEXT

A genetic fingerprint has a neighborhood.

After a sample is genotyped, PCA gives it a visual neighborhood inside the RADseq cohort. Nearby points suggest closer genetic similarity; distant points suggest separation.

Genetic Similarity Map

Public evidence samples are shown in a shared Plotly PCA view so users can inspect genetic neighborhoods without exposing raw genotype data.

How to Read This Graph

Nearby points are genetically closer.

Use the map to see whether a sample sits near other submitted samples or stands apart. The map is a visual guide to similarity, not the final identity decision.

Technical context: this display is a PCA view generated from RADseq marker data and interpreted alongside direct pairwise similarity metrics.

This view is meant for orientation: it helps explain genetic neighborhoods at a glance and gives the viewer a quick sense of relatedness before the deeper report.

HOW IT WORKS

Five steps from tissue to the Forensic Identity Dossier.

The workflow starts with a sample record, produces marker data, compares genetic relationships, and documents the result in a bounded dossier.

01

Submit a sample

Plant tissue is collected with cultivar metadata so the sample can be tracked through analysis.

02

Generate SNP data

Independent laboratory processing produces genome-wide marker data suitable for identity and relatedness analysis.

03

Build the fingerprint

Many SNP markers are combined into a multilocus profile that represents the submitted genotype.

04

Analyze relationships

Population-genetic methods compare the sample against the dataset to identify matches, near neighbors, and broader structure.

05

Document the result

The resulting record documents the identity profile, the analysis context, and how the sample compares inside the True Cut system.
