Genetic Pleiotropy
Genetic pleiotropy refers to a single gene influencing multiple, seemingly unrelated traits in cannabis plants. In breeding contexts, this phenomenon means that selecting for one desired characteristic—such as resin production or flowering time—may inadvertently affect other phenotypic expressions like plant structure, terpene ratios, or vigor. Breeders working in cannabis genetics must account for pleiotropy when stabilizing lines, as trait linkage can complicate predictability across generations. Understanding pleiotropy is essential for developing stable cultivars, particularly when multiple traits are valued in target genotypes. This concept underpins modern marker-assisted selection and genomic breeding approaches in cannabis research.

Breeders use knowledge of pleiotropy to predict secondary outcomes when selecting parents or evaluating segregating populations. Mapping linkage groups helps identify which traits are genetically coupled, allowing more informed crossing decisions and faster route to stable, multi-trait cultivars.
