Genetic Homozygosity
Genetic homozygosity refers to a condition where an organism carries identical alleles at a given locus—meaning both copies of a gene are the same. In cannabis breeding, homozygous plants are valued for trait stability, as they reliably pass consistent characteristics to offspring. Breeders working toward fixed lines intentionally select and stabilize homozygous individuals across multiple generations. This contrasts with heterozygous plants, which carry different alleles and produce more variable progeny. Homozygosity is fundamental to creating true-breeding cultivars and uniform seed populations, though it may reduce genetic diversity within a line.

Breeders use homozygous selection as a core strategy for stabilizing desired phenotypes—whether morphology, terpene profiles, or flowering time. Inbreeding programs and repeated self-crossing are common techniques to increase homozygosity and lock in target traits across generations.
