Allele Interaction
Allele interaction refers to how different genetic variants at multiple loci influence terpene expression in cannabis plants. Rather than a single terpene, this describes the genetic mechanism where two or more alleles interact epistatically—meaning one allele's effect depends on the presence or absence of another. Breeders working with stable lineages often observe that terpene profiles shift unpredictably across generations due to these interactions, even when parent plants show consistent aromatic traits. Understanding allele interaction is central to predictive breeding, as it explains why offspring don't always phenotypically match parental terpene ratios. This polygenic model applies broadly across monoterpenes (limonene, myrcene, pinene) and sesquiterpenes (caryophyllene, humulene), making it foundational to modern cannabis genetics.

Breeders leverage allele interaction studies to stabilize terpene expressions across lines and predict trait segregation in F2 and backcross generations. Mapping these interactions helps explain hidden terpene phenotypes and informs selection strategies for targeted aromatic profiles.
