F1 F2 Segregation
F1 and F2 segregation describes the predictable inheritance patterns observed across successive generations in cannabis breeding. When two genetically distinct parent plants are crossed, their F1 offspring typically display uniform traits (often heterozygous). F2 generation plants—produced by selfing or crossing F1s—exhibit trait segregation and recombination, revealing hidden recessive alleles. These patterns follow Mendelian inheritance principles and are foundational to understanding cannabis genetics. Breeders leverage F1/F2 dynamics to identify desirable trait combinations, stabilize line characteristics, and predict phenotypic expression across populations.

F1 uniformity is prized for commercial consistency and hybrid vigor, while F2 segregation allows breeders to isolate and select stable recessive traits for future line development. Understanding segregation ratios helps breeders design crosses strategically and estimate the number of generations required to fix desired characteristics.
