Single Cannabinoid Expression
Single Cannabinoid Expression refers to cannabis plants that produce predominantly one major cannabinoid—typically THC or CBD—while showing minimal expression of secondary cannabinoids. This phenotype arises from specific genetic backgrounds and allelic combinations that suppress or redirect biosynthetic pathways away from minor cannabinoid production. Lineage records frequently report this trait in deliberate breeding programs targeting pharmaceutical or research applications. Plants exhibiting single cannabinoid dominance often display narrower terpene profiles and more predictable chemical consistency across generations. The trait is useful for understanding cannabinoid biosynthesis genetics, though most traditional landrace and heirloom varieties express multiple cannabinoids simultaneously.

Breeders working toward high-potency or cannabinoid-isolate crops select for single cannabinoid expression through backcrossing and phenotype screening. Understanding the genetic basis of this trait—particularly epistatic interactions and CBDAS/THCAS enzyme regulation—informs molecular breeding and cultivar standardization.
