Genetic Dimorphism

Genetic dimorphism in cannabis refers to the expression of distinctly different phenotypes from the same genotype, often influenced by environmental conditions, epigenetic factors, or sex-linked traits. In breeding contexts, breeders working in this category observe how identical genetic material can produce plants with notably different plant structures, leaf morphologies, or terpene profiles depending on cultivation variables. This phenomenon is particularly relevant when stabilizing seeds or selecting for consistent traits across generations. Understanding genetic dimorphism helps breeders predict phenotypic variation and design more stable cultivars. Documentation of dimorphic expression patterns contributes to the broader knowledge of cannabis genetics and the interplay between genotype and environment.

Breeders track genetic dimorphism to identify which traits are environmentally influenced versus genetically fixed, allowing for more targeted selection in stabilization programs. Recognizing dimorphic patterns helps prevent false culling and supports the development of more uniform seed lines.
