Genetic Fixation
Genetic fixation refers to the breeding state where a trait or allele reaches 100% frequency in a population, meaning all individuals carry identical genetic material at that locus. In cannabis breeding, fixation is a key goal when stabilizing desired characteristics—whether morphology, cannabinoid ratios, or terpene profiles—across generations. Breeders achieve fixation through selective breeding, backcrossing, or inbreeding protocols over multiple generations. Once a trait is fixed, it breeds true in offspring without segregation or variation. This concept is fundamental to creating stable, uniform cultivars that consistently express predictable phenotypes. Understanding fixation helps breeders design breeding programs and manage genetic diversity strategically.

Breeders deliberately work toward fixation when establishing stable lines or IBL (inbred line) cultivars. Fixation is critical for commercializing consistent products and understanding what traits are genetically locked versus environmentally influenced.
