F2 Segregation
F2 segregation refers to the genetic splitting patterns observable in second-generation (F2) cannabis offspring, where recessive traits resurface after being masked in F1 hybrids. This occurs when two heterozygous F1 plants are crossed, allowing recessive alleles to express themselves in predictable Mendelian ratios—typically 3:1 phenotypic splits for single-gene traits. Breeders monitoring F2 populations often observe terpene profile variations, cannabinoid ratios, and morphological diversity that weren't apparent in the F1 generation. Understanding F2 segregation is foundational to selective breeding programs, as it reveals hidden genetic potential and allows stabilization of desired trait combinations across multiple generations.

F2 populations are critical in cannabis breeding because they expose recessive alleles controlling terpene production, plant structure, and yield characteristics. Breeders intentionally grow F2 lines to identify and select individuals carrying desired recessive traits before advancing toward F3, F4, or IBL (inbred line) stability.
