Sex Specific Morphology

Sex-specific morphology refers to observable physical differences between male and female cannabis plants beyond reproductive structures. Female plants typically develop wider, bushier branch angles and denser internodal spacing, while males often exhibit taller, more linear growth patterns with longer internodes. These traits emerge during vegetative development and become more pronounced as plants approach flowering. Breeders leverage morphological dimorphism when selecting parent plants, as female architecture often correlates with desired canopy density and flower site distribution. Understanding these distinctions helps cultivators identify sex earlier in development and informs breeding strategy around plant structure preferences.

Breeders selectively work with sex-specific structural traits to stabilize desired plant architecture in cultivars. Female morphology—particularly branching patterns and internode length—directly influences yield potential and canopy management, making it a deliberate selection criterion in many breeding programs.
