Homozygous Dominant

Homozygous dominant is not a terpene, but a genetic condition where an organism carries two identical dominant alleles for a given trait. In cannabis breeding, this term describes plants that express a dominant phenotype consistently and pass that trait reliably to offspring. Breeders working toward stable, true-breeding lines often select for homozygous dominant individuals across desired traits—whether morphology, resin production, or terpene profiles. Understanding zygosity is foundational to predictable breeding outcomes and strain stabilization.

Breeders prioritize homozygous dominant individuals when establishing F1 hybrids or IBL (inbred line) standards, as these plants breed true and reduce phenotypic variation in subsequent generations. Stabilizing lines around homozygous dominant genotypes is essential for commercial seed production and trait reliability.
