Genotype Phenotype

Genotype-phenotype relationships describe how a cannabis plant's genetic code (genotype) expresses visible traits and aromatic profiles (phenotype). A single genetic strain can produce multiple phenotypic expressions depending on environmental conditions, growing techniques, and epigenetic factors. Breeders distinguish between genetic potential and actual expression when documenting aroma profiles, recognizing that identical seeds may develop different terpene ratios under varied light, temperature, or soil conditions. Understanding this distinction is critical for reproducible cultivation and accurate strain documentation. This framework helps explain why the same named variety sometimes exhibits notably different aromatic character across different growing regions or harvests.

Breeders use genotype-phenotype analysis to identify stable genetic lines versus phenotypically variable ones, informing selection strategies for consistency. Documenting which environmental factors trigger specific aromatic expressions helps establish protocols for reliably reproducing desired terpene profiles across generations.
