Single Note Dominance

Single Note Dominance refers to cannabis plants exhibiting one overwhelmingly prominent terpene or aromatic compound that masks or subdues secondary aromatic profiles. In lineage records, strains like Myrcene-Forward cultivars (such as certain OG Kush phenotypes) or Limonene-Heavy selections frequently report this trait. Breeders working in this category often select parent plants showing extreme terpene skew across multiple generations to stabilize a distinctive, narrow sensory signature. This genetic architecture contrasts with balanced or complex multi-terpene profiles, offering a simplified genetic target for selective breeding programs. Single Note Dominance can emerge from both deliberate selection pressure and natural genetic bottlenecks in closed breeding populations.

Breeders leverage Single Note Dominance to establish consistent, recognizable cultivar identities and to explore the biochemical limits of terpene biosynthesis in cannabis. Stabilizing a dominant note allows for reliable phenotype prediction across seed crops and clonal propagation, reducing phenotypic variance in commercial breeding.
