Intersex Phenotype

Intersex phenotype refers to cannabis plants that express both male and female reproductive structures, a condition sometimes called hermaphroditism in cultivation contexts. This occurs when environmental stress, genetic predisposition, or developmental factors trigger the formation of pollen-producing staminate flowers alongside pistillate (female) flowers on the same plant. Breeders and cultivators distinguish between true intersex genetics and stress-induced reversions, as the stability and heritability differ significantly. Understanding intersex expression is critical for seed production programs, breeding line maintenance, and crop planning in regulated cultivation. Documentation of intersex occurrence helps breeders identify environmental triggers and select for or against the trait depending on breeding goals.

Breeders working with feminized seed production intentionally select for mild intersex traits or stress-responsive male flower production to create female plants that produce viable pollen for breeding. Conversely, photoperiod and regular seed programs aim to minimize unwanted intersex expression through environmental control and genetic selection for stability.
