Heterozygous Homozygous
Heterozygous and homozygous describe allelic states at individual genetic loci, not aromas themselves. Homozygous plants carry identical alleles for a trait (AA or aa), while heterozygous plants carry different alleles (Aa). In cannabis breeding, these genetic states influence the stability and expression of aroma-related terpene genes across generations. Breeders track homozygosity to predict offspring consistency; fully homozygous lines typically breed true, while heterozygous plants may produce variable terpene profiles in F1 crosses. Understanding these genetic foundations helps breeders develop stable aroma phenotypes.

Breeders working toward stable, repeatable terpene profiles prioritize homozygous lines because they reliably pass aroma traits to offspring. Conversely, heterozygous F1 hybrids often display hybrid vigor and novel aroma combinations, but require continued selection to stabilize desired terpene characteristics across generations.
