Cannabis Genetics Classification

Cannabis genetics classification refers to the systematic categorization of cannabis plants based on morphology, chemotype, and lineage. Modern classification frameworks distinguish between sativa, indica, and ruderalis subspecies, though these categories have been refined by contemporary genetic sequencing and breeding records. Breeders and geneticists recognize that traditional morphological descriptions (tall/thin versus short/dense) correlate imperfectly with cannabinoid and terpene profiles. Classification also encompasses chemotype distinctions—THC-dominant, CBD-dominant, and balanced strains—which are determined by inherited genetic pathways. Understanding these frameworks helps breeders predict trait inheritance and maintain accurate lineage records across generations.

Breeders use genetic classification systems to select parent plants, predict offspring characteristics, and document strain stability and purity. Accurate classification supports reproducible breeding programs and helps identify which traits are likely to express in F1 and subsequent generations.
