Genetic Dominance
Genetic dominance describes the inheritance pattern where one allele's expression masks or suppresses another allele's phenotype in heterozygous organisms. In cannabis breeding, dominance patterns affect how traits—including morphology, terpene profiles, and cannabinoid ratios—manifest across generations. Breeders track dominant and recessive traits to predict F1, F2, and backcross outcomes. Understanding dominance hierarchies is essential for stabilizing desired characteristics and avoiding trait segregation in subsequent generations. Most commercial cannabis varieties exhibit complex polygenic inheritance rather than simple single-gene dominance, making phenotypic prediction nuanced.

Breeders exploit dominance patterns to rapidly fix desirable traits in F1 hybrids or to maintain genetic diversity through strategic recessive trait preservation. Predictive dominance mapping helps optimize breeding programs, reduce unwanted trait expression in offspring, and stabilize heterozygous vigor (hybrid vigor) across multiple generations.
