Thc Dominant Phenotypes

THC-dominant phenotypes represent cannabis plants expressing higher concentrations of delta-9-tetrahydrocannabinol relative to cannabidiol and other minor cannabinoids. These phenotypes emerge through selective breeding targeting CB1 receptor-active compounds and are the most common expression in modern cannabis cultivar development. Lineage records frequently report THC dominance in popular strain families including Kush, Haze, and hybrid crosses refined over decades. Breeders distinguish THC-dominant expressions from balanced or CBD-dominant chemotypes through cannabinoid profiling and plant selection across generations. Understanding phenotypic expression requires attention to genetic potential, environmental factors, and breeding methodology rather than assuming lineage alone predicts cannabinoid ratios.

Breeders working with THC-dominant genetics prioritize selection for cannabinoid synthase enzyme activity and plant material demonstrating consistent high-THC expression across generations. Maintaining stable THC-dominant lines requires careful phenotype hunting, backcrossing, and environmental standardization to preserve target cannabinoid profiles in seed stock.
