Phenotypic Segregation
Phenotypic segregation refers to the visible variation in plant traits—leaf shape, flower density, growth rate, terpene expression—that emerges across offspring from the same parent cross. This occurs because cannabis, like most plants, carries multiple alleles for a single trait; when F1 hybrids are selfed or crossed, recessive traits often re-emerge in F2 and F3 generations. Breeders working with stabilized or heirloom lines frequently observe segregation patterns that reveal hidden genetic diversity. Understanding segregation is essential for identifying keeper phenotypes and predicting trait stability across generations. Documented segregation can inform breeding strategies for both trait fixation and diversity preservation.

Breeders exploit phenotypic segregation to isolate stable lines with desired terpene profiles, structure, and vigor. Mapping segregation ratios helps identify whether traits are controlled by single or multiple genes, guiding decisions on backcrossing, selfing, or multi-generational selection.
