Trait Inheritance

Trait inheritance describes how genetic characteristics pass from parent plants to offspring in cannabis breeding programs. In sexually reproducing cannabis, traits follow predictable patterns based on whether they're controlled by dominant or recessive alleles, single genes or multiple genes, or influenced by environmental factors during growth. Breeders document inheritance patterns to understand which parental traits reliably express in filial generations, helping predict phenotypic outcomes and stabilize desired characteristics across breeding lines. Understanding trait inheritance is foundational to selective breeding, as it allows cultivators to make informed decisions about which plants to cross and what genetic stability to expect in resulting seeds or clones.

Breeders use trait inheritance knowledge to plan crosses strategically—selecting parents with complementary traits and predicting whether offspring will exhibit target characteristics in F1, F2, or later generations. Mapping inheritance patterns helps establish stable cultivars and identify whether traits like plant structure, terpene profiles, or flowering time breed true or segregate unpredictab
