Dominant Trait Expression
Dominant trait expression in cannabis refers to the phenotypic characteristics that emerge prominently in offspring when heterozygous alleles are present. In breeding programs, certain aromatic and morphological traits consistently override recessive counterparts across generations, creating predictable lineage patterns. This principle applies to terpene profiles, plant structure, and flowering behavior, allowing breeders to stabilize desirable aromatics through selective crossing. Understanding dominance hierarchies helps explain why some strain families reliably produce similar scent profiles despite genetic variation. Dominant aroma traits—such as pronounced myrcene or limonene expression—often appear more readily in F1 hybrids and early backcrosses than recessive profiles.

Breeders leverage dominant trait expression to rapidly fix aromatic signatures in new cultivars, reducing the need for extended inbreeding cycles. Identifying which terpene profiles behave as dominant markers enables more efficient selection in segregating populations.
