Heterozygous
Heterozygous describes a cannabis plant carrying two different alleles (gene variants) at a given locus on its chromosome pair. In breeding contexts, a heterozygous individual expresses the dominant trait while carrying a recessive allele that may appear in offspring. This genetic state is foundational to understanding trait segregation in F1 hybrids and backcrosses. Heterozygous plants typically show hybrid vigor and phenotypic consistency within a generation, but their offspring will segregate into multiple phenotypes. Most commercial cultivars are maintained as heterozygous lines to preserve stability and desired trait expression across multiple growing cycles.

Breeders leverage heterozygous individuals to create stable F1 hybrids with predictable phenotypes and enhanced vigor. Understanding whether a parent plant is heterozygous or homozygous at key trait loci is essential for predicting offspring characteristics and designing selective breeding programs that stabilize desired genetics.
