The graphic above displays each of the strains that have been genetically sequenced using the StrainSEEK™ Strain Identification and Registration Service. The placement of each strain on the graphic is determined by its genetic distance to the others. Genetic distance is a measure of the genetic divergence between cannabis strains. Strains with many similar alleles have small genetic distances, indicating they are closely related and have a recent common ancestor.
Hovering over a strain of interest will highlight it along with any other strain that is within a genetic distance of 8. The color of the highlight on the related strains indicates how closely they are related to the strain of interest.
- Red: 0 – 1.8
- Orange: 1.9 – 3.7
- Yellow: 3.8 – 5.5
- Green: 5.6 – 7.3
- Blue: 7.4 – 8
As you can see, a strain’s proximity to another on the graphic does not necessarily indicate they are closely related. To get a better sense of how the strains relate, follow the branches back to the center of the tree.
