Allelic Frequency
Allelic frequency describes the proportion of different genetic variants (alleles) present within a cannabis population at a given locus. In breeding work, allelic frequency shifts across generations as breeders select for desired traits—cannabinoid profiles, morphology, disease resistance, or terpene expression. Understanding allelic frequency helps breeders predict trait stability, identify genetic bottlenecks, and maintain genetic diversity within curated lines. High-frequency alleles tend to fix quickly in closed breeding programs, while rare alleles may be lost unless actively preserved. Population genetics models rely on allelic frequency data to track how selection pressure reshapes a strain family over multiple generations.

Breeders monitor allelic frequency shifts to balance trait fixation with genetic resilience. Tracking frequency changes across backcrosses, crosses, and stabilization rounds informs decisions about selection intensity, outcrossing, and conservation of minor alleles that may encode valuable secondary traits.
