Xx Chromosome Expression
XX chromosome expression refers to the genetic presentation of female cannabis plants, where both X chromosomes are expressed in cellular function. In dioecious cannabis populations, XX individuals typically develop as phenotypic females capable of producing flowers and seeds. Chromosome expression patterns influence plant morphology, flowering characteristics, and secondary metabolite production, though environmental factors also significantly impact phenotypic outcomes. Breeding programs track XX expression to maintain female-line stability and understand trait inheritance across generations. This classification remains relevant in regulated seed production and preservation of established cultivar genetics.

Breeders working with XX chromosome expression focus on stabilizing female-only populations and understanding how X-linked traits transmit through maternal lineages. Tracking XX expression helps distinguish true-breeding female lines from feminized or intersex individuals in multi-generational selection programs.
