Thca Synthase Dominance
THCA synthase dominance refers to genetic expression favoring cannabinoid synthase enzymes that prioritize THCA (tetrahydrocannabinolic acid) production over CBDA pathways. This trait is determined by allelic variation in genes encoding cannabinoid synthases, particularly affecting the ratio of THCA to other acidic cannabinoids at harvest. Breeders working with THCA-dominant genetics often observe chemotypes expressing 15%+ THCA with minimal CBDA levels. The phenotype is biochemically distinct from simple THC potency, as it reflects pre-decarboxylation cannabinoid synthesis priorities. Understanding synthase dominance helps breeders predict cannabinoid profiles across environmental conditions and filial generations.

Breeders select for THCA synthase dominance when developing lines targeting specific cannabinoid ratios. This trait shows moderate heritability and is useful for stabilizing chemotypes across cultivation environments.
