Genotype Versus Phenotype

Genotype refers to the genetic code inherited from parent plants, while phenotype is how those genes physically express under specific environmental conditions. In cannabis breeding, two plants with identical genotypes may develop notably different aromas, flavors, and structures depending on temperature, humidity, light, and soil composition. Breeders carefully distinguish between stable genetic traits and environment-dependent expressions when selecting parent stock. Understanding this distinction is critical for consistent seed production and for identifying which aromatic characteristics are heritable versus transient. This knowledge helps breeders reliably predict offspring traits and stabilize desired lineages across generations.

Breeders use genotype-phenotype literacy to isolate stable aromatic markers for selection, ensuring that prized scent profiles breed true in subsequent generations. Seed companies document phenotypic variation ranges to educate growers about expected environmental triggers and help predict aromatic outcomes across different cultivation settings.
