Genotype Vs Chemotype

Genotype and chemotype represent two distinct but interconnected ways breeders classify cannabis plants. Genotype refers to the plant's underlying genetic makeup—the DNA sequences inherited from parent plants. Chemotype describes the plant's chemical expression, particularly its terpene and cannabinoid profile, which results from both genotype and environmental conditions. A single genotype can produce different chemotypes depending on cultivation variables like temperature, light, and soil composition. Understanding this distinction is critical for breeding programs seeking stable, predictable aromatic profiles across growing conditions.

Breeders use genotype-chemotype relationships to identify stable genetics that reliably express target terpene profiles. By growing multiple phenotypes from the same genetic line and analyzing their chemical outputs, breeders can select parents likely to produce offspring with consistent aromatic signatures across diverse growing environments.
