Genetic Expression Environmental Factors

Genetic expression in cannabis is significantly influenced by environmental factors during cultivation, affecting both terpene profiles and plant phenotypes. Temperature, light intensity, humidity, and soil composition interact with a plant's underlying genetics to determine which genes are activated or suppressed. This phenomenon means that identical genetic material can produce notably different terpene concentrations and aromatic profiles across different growing conditions. Understanding these interactions is foundational to cannabis breeding, as it helps distinguish stable genetic traits from environmentally-induced variations. Breeders carefully document environmental conditions during selection to ensure they're identifying heritable characteristics rather than temporary phenotypic expressions. This knowledge informs decisions about which plants merit inclusion in breeding program

Breeders track environmental standardization during phenotype selection to accurately assess genetic potential versus environmental influence. This distinction is critical when identifying stable terpene producers or consistent growth characteristics for future crosses.
