Metabolic Pathway Dominance

Metabolic pathway dominance refers to the genetic predisposition of cannabis plants to favor certain biochemical routes during secondary metabolite production. Different cultivars and lineages show variable expression patterns in cannabinoid synthesis, terpene biosynthesis, and flavonoid accumulation—traits controlled by multiple genes and environmental factors. Breeders studying these pathways observe that some genetics consistently channel resources toward cannabinoid production, while others emphasize terpene or phenolic compound development. Understanding these metabolic patterns is valuable for predictive breeding and stabilizing desired chemical profiles across generations. Lineage documentation and phytochemical testing help identify which parent plants demonstrate strong pathway expression. This category encompasses the genetic architecture underlying chemotype variation in canna

Breeders working with metabolic pathway dominance select parent plants that consistently express preferred biochemical outputs, then track offspring to identify which individuals inherit and amplify those traits. Combining parents with complementary metabolic strengths—such as one favoring cannabinoid synthesis and another showing robust terpene production—allows targeted development of novel cult
