Cannabinoid Segregation
Cannabinoid segregation refers to the genetic tendency of offspring to express distinct cannabinoid profiles that differ markedly from their parents—a phenomenon rooted in the complex polyploid inheritance and epistatic interactions governing THC, CBD, and minor cannabinoid biosynthesis. Cannabis exhibits significant locus-level variation across chromosomal regions controlling cannabinoid synthase genes (THCA/CBDA synthase), and crossing plants with differing ratios often produces F1 and F2 generations with unpredictable cannabinoid outcomes. Breeders working in this space have documented cases where high-THC × high-CBD crosses yield offspring expressing intermediate, high-THC dominant, or high-CBD dominant phenotypes in ratios that frequently deviate from simple Mendelian predictions. This segregation pattern is crucial for understanding seed-run variability and is a primary driver of p

Understanding cannabinoid segregation allows breeders to predict and select for desired cannabinoid ratios across generations, though the trait's polygenic nature requires multi-generational selection and test crosses to stabilize desired phenotypes. Seed-run consistency depends heavily on parental cannabinoid genotypes and environmental factors, making segregation mapping and backcrossing essenti
