Heterozygous Lines
Heterozygous lines are cannabis breeding populations in which individual plants carry two different alleles at one or more genetic loci. Unlike homozygous lines—where both alleles are identical—heterozygous lines retain genetic variation within their genomes, producing offspring with phenotypic diversity even within a single generation. Breeders intentionally maintain or create heterozygous populations to preserve genetic potential, enable continued selection pressure, and avoid inbreeding depression. These lines are foundational to modern cannabis breeding programs, serving as F1 hybrid parents or segregating populations where desired traits can be identified and isolated across multiple grows.

Heterozygous lines allow breeders to express recessive traits, test for hidden genetic variation, and generate phenotypic diversity necessary for selection work. Maintaining heterozygosity at key loci delays fixation, keeping breeding lines genetically flexible and responsive to environmental or market demands.
