Allele Pairing

Allele pairing refers to the genetic combination of two alleles at a single locus that influence terpene expression in cannabis plants. Rather than describing a specific terpene, this term addresses the foundational genetics determining whether terpene profiles appear, intensify, or remain recessive across generations. Breeders working with stable lineages track allele pairing to predict terpene phenotypes and maintain consistency in offspring. Understanding allele interactions—dominant, recessive, and codominant—is essential for selecting parent plants that will reliably express desired aromatic compounds.

Breeders use allele pairing models to stabilize terpene expression in F1 hybrids and inbred lines. By crossing plants with known allelic combinations, they can increase the likelihood of offspring exhibiting target aromatic profiles across multiple generations.
