Cannabinoid Synthase Dominance

Cannabinoid synthase dominance refers to the genetic expression patterns that determine which enzymatic pathways are most active in a plant's cannabinoid production. Plants with strong cannabinoid synthase expression tend to accumulate higher concentrations of THC, CBD, or CBG depending on which synthase genes are most robustly transcribed. Breeders studying this trait examine genetic markers and enzymatic activity to predict cannabinoid ratios in offspring. This dominance pattern is inherited but influenced by environmental factors during cultivation. Understanding synthase activity helps breeders develop lines with consistent, predictable cannabinoid profiles across generations.

Breeders working in cannabinoid genetics select parent plants based on synthase expression patterns to lock in desired cannabinoid ratios. Lineage records and genetic testing increasingly document synthase dominance as a core breeding target, especially for lines developed toward specific THC:CBD ratios or rare cannabinoid profiles.
