Type Ii Classification

Type II classification refers to cannabis plants expressing both cannabinoid pathways simultaneously, producing measurable levels of both THC and CBD in the same flower. This intermediate phenotype exists along the cannabinoid spectrum between Type I (THC-dominant) and Type III (CBD-dominant) plants. The ratio of THC to CBD varies considerably among Type II specimens, influenced by genetics, environment, and enzymatic expression of key synthase genes. Type II plants result from complex inheritance patterns and are commonly observed in hybrid breeding programs crossing diverse genetic backgrounds. Lineage records frequently report Type II expressions in strains developed from crosses between high-THC and high-CBD parent lines.

Breeders working in the Type II category pursue these plants for research into cannabinoid ratios, terpene-cannabinoid interactions, and creating genetic baselines for controlled breeding. Understanding Type II expression helps breeders map epistatic interactions and develop breeding populations with predictable intermediate cannabinoid profiles.
