Homozygosity
Homozygosity refers to a plant carrying identical alleles at a given locus—both inherited copies are the same. In cannabis breeding, homozygous lines are prized for genetic stability because offspring reliably express parental traits across generations. This contrasts with heterozygous plants, which carry different alleles and produce variable offspring. Breeders pursuing true-breeding cultivars or stable IBL (inbred line) genetics prioritize homozygosity through repeated self-pollination or sibling crosses. Homozygous lines form the genetic foundation for consistent seed production and predictable phenotypic expression.

Homozygous breeding stock enables breeders to fix desired traits—structure, aroma profiles, terpene ratios, flowering time—into stable lines. Creating homozygous parents through inbreeding is foundational for producing F1 hybrids with uniform vigor and trait expression, as well as developing open-pollinated cultivars and IBLs.
