Genotype

Genotype refers to the genetic makeup of a cannabis plant—the complete set of DNA instructions inherited from parent plants, distinct from the phenotype, which is how those genes express visibly in the environment. Understanding genotype is foundational to cannabis breeding, as breeders select for specific genetic markers to stabilize desired traits across generations. Genotype determines potential cannabinoid and terpene profiles, growth patterns, and environmental resilience, though final expression depends on cultivation conditions. Breeders working with established lineages often reference genotypic stability when describing how consistently offspring match parental characteristics. Seed selection, backcrossing, and inbreeding programs all leverage genotypic knowledge to achieve reproducible results.

Breeders use genotypic analysis to identify which genetic lines carry target traits, enabling informed parent selection and controlled hybridization. Stabilized genotypes—those that reliably produce consistent offspring—are the foundation of reliable seed stock and commercial cultivar development.
