Plant Sex Expression
Plant sex expression in cannabis refers to the phenotypic manifestation of sexual characteristics across the spectrum from male to female, including hermaphroditic presentations. Cannabis is typically dioecious, meaning individual plants produce either male (pollen-bearing) or female (seed-bearing) flowers, though environmental stress, genetic predisposition, and breeding history can trigger expression of both sexes on a single plant. Understanding sex expression is foundational to cannabis breeding, seed production, and cultivation planning. Breeders intentionally select for stable sex expression to maintain predictable crop outcomes, while cultivators must identify and manage plants based on their reproductive role in the garden.

Breeders actively select lines for sexual stability to reduce hermaphroditic traits in feminized and regular seed populations. Stabilizing sex expression across generations is critical for producing reliable cultivars and preventing unintended pollination in breeding programs.
