Dominant Recessive Terpenes

Dominant and recessive terpene expression in cannabis refers to how terpene profiles are inherited and expressed across generations. In genetic terms, certain terpenes may be controlled by dominant alleles that express consistently, while others require two recessive alleles to manifest phenotypically. Breeders working with terpene inheritance have observed that some aromatic profiles (like myrcene-dominant chemotypes) appear frequently across progeny, suggesting dominant genetic control, while rarer terpene combinations require targeted crosses to stabilize. Understanding these inheritance patterns is foundational to cannabis breeding programs aiming to reliably produce specific aromatic profiles. Documentation of terpene heritability remains incomplete due to limited peer-reviewed research, but lineage records and breeder observations provide practical frameworks for predicting offspri

Breeders leverage knowledge of dominant and recessive terpene inheritance to stabilize desired aromatic profiles across multiple generations. By identifying which terpenes breed true versus which require specific crosses, cultivators can design parent selection strategies that increase the probability of target chemotypes in F2 and F3 generations.
