Gene Flow
Gene flow in cannabis breeding refers to the movement of genetic material between different plant populations, strains, or cultivars through pollination and seed production. In controlled breeding programs, gene flow is deliberately managed to introduce desirable traits from one lineage into another, or conversely, isolated to maintain genetic purity within a closed population. Uncontrolled gene flow—such as cross-pollination between adjacent outdoor grows—can alter intended strain characteristics and complicate lineage records. Breeders working with cannabis genetics carefully document and control gene flow patterns to achieve consistent offspring and preserve breeding integrity across generations.

Understanding gene flow is essential for strain stabilization, backcrossing programs, and maintaining F1 hybrid vigor. Breeders deliberately limit or enhance gene flow depending on whether they seek genetic diversity or strain uniformity.
