F2 Segregation
F2 segregation refers to the genetic variation observed in the second filial generation (F2) when F1 hybrid plants are self-pollinated or crossed with one another. In cannabis breeding, F2 populations display significantly increased phenotypic diversity compared to their F1 parents, as recessive traits and allele combinations re-emerge according to Mendelian inheritance patterns. This generation is critical for identifying stable trait expression, locating undesired recessive characteristics, and selecting foundation plants for line stabilization. F2 work requires larger population sizes to reliably identify and isolate desired phenotypes, making it a resource-intensive but genetically informative phase in breeding programs.

Breeders commonly use F2 segregation to map trait inheritance, identify homozygous individuals for specific characteristics, and establish the genetic architecture of their crosses. F2 selection data directly informs decisions about backcrossing, inbreeding, or population advancement toward stable IBL (inbred line) status.
