Genetic Testing For Strain Verification
Genetic testing services have started offering strain verification, where a leaf sample is sequenced and compared against a database of known cultivars. It cannot tell you the exact breeder, but it can flag when a supposed pure Thai line shares most of its markers with a common Skunk hybrid. The verification section on https://hazesativaseeds.com lists a few labs, the rough cost per sample, and the caveats about how thin the reference database still is for rare landrace lines. It is mostly useful for settling arguments about whether a cut is genuinely what it was sold as.
