Genotype Classification

Genotype classification refers to the genetic makeup of a cannabis plant, distinct from its observable characteristics (phenotype). Breeders use genotype data to understand inheritance patterns, predict offspring traits, and maintain genetic records across generations. Modern genotype classification often involves marker-assisted selection and DNA testing to identify parent plants and verify lineage authenticity. Understanding genotype classification is foundational to cannabis breeding programs, helping breeders work with stable lines, create consistent F1 hybrids, and document genetic diversity within strain families. Genotype information typically remains invisible to growers until flowering reveals phenotypic expression, making genetic testing a critical tool in professional breeding operations.

Breeders rely on genotype classification to select parents with complementary genetic traits, stabilize desirable characteristics across multiple generations, and avoid unintended genetic drift. Accurate genotype records enable predictable hybrid crosses and help distinguish between phenotypically similar plants that carry different underlying genetics.
