Stability And Segregation

Stability and Segregation refers to the breeding practices and genetic principles governing how cannabis traits express and pass through successive generations. In formal genetics, stability describes a plant line's consistency across generations, while segregation refers to how alleles distribute during reproduction—particularly important in cannabis where polyploidy and outcrossing histories create complex inheritance patterns. Breeders working in this category track trait stability through F1, F2, and stabilized lines to understand which characteristics breed true and which require ongoing selection. Segregation patterns help identify whether desired traits are dominant, recessive, or sex-linked, informing strategies for line development and seed production.

Understanding segregation allows breeders to predict offspring phenotypes and identify homozygous versus heterozygous individuals. Stabilized lines—where key traits consistently express across generations—form the foundation for reliable cultivar development and commercial seed offerings.
