Cannabis Phylotree



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 (Clones)
  • Orange: 1.9 – 3.7 (Siblings)
  • Yellow: 3.8 – 5.5 (Cousins)
  • Green: 5.6 – 7.3 (Distant relationship)
  • Blue: 7.4 – 8 (Breed with me for diversity)

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.
