Sex Determination Genetics
Sex determination in cannabis is governed by chromosomal and environmental factors that breeders and cultivators carefully manage. Most commercial cannabis plants are female, valued for flowering resin production, while male plants are essential for breeding programs and pollen production. Cannabis exhibits XY sex determination, though environmental stress, photoperiod, and genetic background can influence phenotypic sex expression. Understanding sex determination is critical for seed production, breeding strategy, and cultivation planning. Breeders working in this category often develop feminized seed lines and monitor environmental conditions to control plant sex ratios in breeding populations.

Breeders exploit sex determination genetics to create feminized seed lines that reliably produce female plants, reducing cull rates in commercial cultivation. Knowledge of sex reversal techniques and genetic sex markers allows breeders to accelerate male trait selection, preserve rare genotypes, and maintain breeding stock efficiency.
