F2 Segregation Patterns
F2 segregation patterns describe the genetic distribution observed in the second filial generation when homozygous parent plants are crossed, then their offspring self-pollinated or intercrossed. These patterns follow Mendelian inheritance principles, with traits appearing in predictable ratios (typically 3:1 for single-gene traits, or 9:3:3:1 for two-gene traits). In cannabis breeding, F2 populations reveal hidden recessive alleles masked in F1 hybrids, allowing breeders to identify and select for desired characteristics. Understanding F2 segregation helps breeders assess trait stability, genetic diversity, and the number of genes controlling complex phenotypes like cannabinoid ratios, terpene profiles, or plant architecture.

Cannabis breeders use F2 lines to stabilize traits and create true-breeding cultivars. Analyzing F2 segregation data informs decisions about which parent plants to advance, whether traits are controlled by one or multiple genes, and the feasibility of developing uniform cultivar lines.
