Dominant Traits

Dominant traits in cannabis genetics are heritable characteristics that consistently express in offspring when inherited from either parent, following Mendelian inheritance patterns. These traits include plant morphology (leaf shape, internode spacing), flowering time windows, and terpene profiles that appear predictably across generations. Breeders identify dominant traits through multi-generational observation and pedigree tracking, as they provide stability in breeding programs. Understanding dominance hierarchies helps predict F1 hybrid vigor and segregation patterns in subsequent generations. Recessive traits may skip generations or only express in homozygous individuals, making dominant trait selection crucial for consistent cultivar development.

Breeders leverage dominant traits to rapidly stabilize desired characteristics in new lines, as these features require fewer selection cycles to fix in a population. Selecting parents with aligned dominant traits accelerates breeding timelines and reduces trait segregation variance in commercial seed production.
