Sex Expression
Sex expression in cannabis refers to the genetic and environmental factors determining whether a plant develops as male, female, or hermaphrodite. While cannabis is typically dioecious (separate male and female plants), environmental stress—including temperature fluctuations, light cycle disruptions, and nutrient imbalances—can trigger hermaphroditic trait expression even in genetically stable female lines. Breeders carefully monitor sex expression stability because inconsistent phenotypic stability can compromise breeding programs and cultivation reliability. Understanding sex expression inheritance patterns is fundamental to maintaining pure female seed lines and identifying genetic vulnerabilities in breeding stock.

Breeders select for stable female expression and screen breeding stock for hermaphroditism tendency to prevent accidental pollination and maintain seed line integrity. Mapping sex expression stability helps identify environmental thresholds and genetic markers associated with phenotypic robustness across growing conditions.
