F1 Segregation
F1 segregation refers to the genetic trait expression pattern observed in first-generation hybrids when crossed back to parental lines or self-pollinated. In cannabis breeding, F1 plants typically display hybrid vigor and stable phenotypes, but their offspring (F2 generation) often show trait splitting—where recessive alleles emerge and create phenotypic variation. This segregation occurs because F1 individuals carry heterozygous (Aa) allele pairs that separate during meiosis. Understanding segregation patterns helps breeders predict which traits will remain stable across generations and which will require continued selection to fix desired characteristics.

Breeders monitor F1 segregation to identify which desirable traits breed true and which require multi-generational stabilization. Observing segregation in F2 and F3 populations reveals whether a trait is controlled by single or multiple genes, informing decisions about line-fixing strategy and stability testing before releasing cultivars.
