Sex Determination Loci
Sex determination loci refer to the genetic regions and chromosomal markers that influence the development of male, female, or intersex cannabis plants. Cannabis exhibits environmental and genetic sex determination, with multiple loci contributing to phenotypic sex expression rather than a single dominant gene. Breeders and researchers track these loci to understand reproductive outcomes, predict sex ratios in seed populations, and develop stable dioecious or monoecious lines. The Y chromosome and autosomal regions both carry genes affecting sexual differentiation, making sex determination a complex polygenic trait. Understanding these loci is essential for breeding programs seeking consistent plant architecture and seed production strategies.

Breeders working with sex determination loci can improve seed line stability, predict flowering sex ratios, and develop feminized or dioecious cultivars with greater precision. Knowledge of these genetic markers supports selection for desired reproductive traits across generations.
