Sativa Dominant Phenotype

Sativa-dominant phenotypes are cannabis plants expressing morphological and growth characteristics typically associated with Cannabis sativa subspecies origins, including taller stature, longer internodal spacing, narrower leaflets, and extended flowering periods. These phenotypes frequently result from crosses where sativa genetics comprise the majority of a plant's lineage, though environmental factors and individual plant expression can influence final phenotype. Breeders working with sativa-dominant cultivars often select for these traits across multiple generations to stabilize and emphasize sativa characteristics. Lineage records commonly show sativa-dominant varieties originating from equatorial and subtropical breeding regions, where such growth patterns reflect adaptation to longer growing seasons.

Breeders utilize sativa-dominant phenotypes to introduce extended flowering windows, vertical growth architecture, and specific terpene profiles into breeding programs. Stabilizing sativa-dominant traits requires careful phenotype selection and multi-generational backcrossing to maintain consistency across seed batches.
