Phenotypic Segregation
Phenotypic segregation refers to the visible expression of different traits across offspring when crossing two parent plants with different genotypes. In cannabis breeding, segregation becomes apparent in F1 and F2 generations, where recessive alleles may re-emerge, producing plants with varied morphology, color, resin production, and aroma profiles even from identical seed stock. Breeders rely on understanding segregation patterns to identify which traits are dominant or recessive, and to select parent plants that will reliably pass desired characteristics to subsequent generations. Proper documentation of segregation ratios helps breeders establish stable, predictable lines and avoid unexpected trait drift in commercial cultivars.

Breeders intentionally monitor phenotypic segregation to map heritable traits, establish inbred lines, and determine whether a desired characteristic is stable or requires further selection pressure. Understanding segregation is essential for creating F1 hybrids with consistent expression and for backcrossing programs aimed at fixing specific traits into a genetic background.
