Heterozygous Expression
Heterozygous expression refers to the observable traits resulting from plants carrying two different alleles at a given locus. In cannabis breeding, this genetic state produces phenotypic variation even within a single cross, as recessive and dominant traits interact unpredictably across offspring. Breeders working with F1 hybrids or heterozygous parent lines frequently observe increased morphological and aromatic diversity compared to homozygous counterparts. This variability can manifest in terpene profiles, plant structure, and flowering time. Understanding heterozygous expression is essential for stabilizing lines and predicting breeding outcomes, though environmental factors also heavily influence final expression.

Breeders exploit heterozygous expression to generate genetic diversity in early generations, then select toward homozygosity in later crosses to create stable cultivars. Recognizing heterozygous phenotypes helps distinguish true-breeding lines from segregating populations.
