Chemotype Segregation
Chemotype segregation refers to the genetic tendency of cannabis populations to produce distinct chemical profiles across generations or within a single generation. Unlike uniform cultivars, genetically diverse parents can produce offspring expressing notably different cannabinoid, terpene, and flavonoid ratios—sometimes yielding high-THC, high-CBD, or balanced chemotypes from the same cross. This phenomenon is particularly evident in F1 and F2 generations where recessive alleles controlling secondary metabolism become visible. Breeders working with landraces or heterozygous parent stock frequently observe chemotype segregation, which complicates phenotype selection but also creates breeding opportunities. Understanding segregation patterns helps explain why seed runs from the same parents don't always produce phenotypically consistent plants.

Breeders leverage chemotype segregation to isolate rare or desirable chemical profiles from genetically diverse crosses. Stabilizing specific chemotypes typically requires multiple generations of selection and backcrossing to fix target allele combinations.
