Genotypic Homozygosity
Genotypic homozygosity describes plants carrying identical alleles at a given locus—meaning both inherited copies of a gene are the same. In cannabis breeding, homozygous lines are valuable because they produce offspring with predictable traits across generations, a foundation for stable cultivars. Breeders commonly work toward homozygosity through repeated self-pollination or deliberate cross-selection to 'fix' desirable characteristics. Homozygous plants are often designated F1 or later generations after stabilization. This contrasts with heterozygous plants, which carry different alleles and produce variable offspring. Understanding homozygosity is essential for developing true-breeding strains and maintaining genetic consistency in seed production.

Breeders pursuing stable, repeatable cultivars prioritize homozygous lines because they reliably transmit phenotypic traits. Homozygous parents are also used in controlled crosses to predict F1 hybrid vigor and phenotypic outcomes with higher accuracy.
