Type I Thc Dominant
Type I THC-dominant cannabis refers to plants that express significantly higher tetrahydrocannabinol (THC) levels relative to cannabidiol (CBD), typically with minimal or trace CBD production. This classification emerged from cannabinoid profiling studies that categorized plants based on their CBDA/THCA synthase enzyme expression patterns. Most modern commercial cannabis strains fall into this category due to decades of selective breeding emphasizing THC-producing pathways. Type I plants are the result of recessive CBD-suppressing genetics becoming fixed in breeding lines. Understanding this chemotype helps breeders recognize underlying genetic architecture and predict cannabinoid expression in offspring.

Breeders working with Type I genetics track THCA synthase dominance to maintain high-THC phenotypes while occasionally incorporating CBD-modifying traits from Type II or Type III genetics. Identifying pure Type I parents helps ensure stable cannabinoid ratios across generations and supports controlled breeding programs.
