Plant Genetics

Plant genetics refers to the hereditary material and trait expression within cannabis cultivars, determining morphology, terpene profiles, cannabinoid ratios, and phenotypic variation. Breeders work with genetic markers and observable traits to document lineage authenticity and predict offspring characteristics. Cannabis genetics are typically inherited through nuclear DNA and cytoplasmic factors, with complex polygenic traits governing most horticultural and chemical profiles. Understanding plant genetics is foundational to seed production, strain stabilization, and maintaining genetic integrity across generations. Lineage records and genetic testing increasingly inform breeding decisions and cultivar documentation in the cannabis industry.

Breeders select for specific genetic traits by crossing parents with desired characteristics, then stabilize lines through selective breeding over multiple generations. Genetic markers and phenotypic observation help breeders verify strain authenticity, predict segregation ratios in F1 and F2 crosses, and maintain genetic purity in seed lines.
