Seed Genetics

Seed genetics refers to the hereditary material and trait expression patterns carried within cannabis seeds, determining plant phenotype, potency markers, growth characteristics, and cannabinoid/terpene profiles. Understanding seed genetics is fundamental to breeding programs, as breeders track dominant and recessive traits across generations to stabilize desired characteristics. Seed genetics encompass both nuclear DNA (inherited from both parents) and maternal cytoplasmic inheritance. Professional cultivators and breeders rely on documented lineage records and phenotypic observation to predict offspring performance. Regular seeds (containing both male and female chromosomes) express full genetic diversity, while feminized seeds are bred to suppress male development through genetic or chemical intervention.

Breeders working in cannabis genetics use seed selection, backcrossing, and phenotype hunting to isolate and stabilize target traits across multiple generations. Understanding seed genetics allows breeders to predict segregation patterns, plan crossing strategies, and maintain genetic integrity within proprietary strain lines.
