Linkage Disequilibrium
Linkage disequilibrium (LD) is a population genetics concept describing non-random inheritance of alleles across cannabis genomic regions. Rather than a terpene itself, LD is a statistical measure of how often specific genetic markers or traits co-segregate in breeding populations. When two loci show LD, alleles at one position predict alleles at another, even if they assort independently by Mendelian rules. This phenomenon is critical in cannabis breeding because favorable traits—including terpene production, cannabinoid ratios, and plant morphology—often cluster together due to limited recombination or founder effects. Understanding LD patterns helps breeders predict trait inheritance and avoid unintended linkage of undesirable characteristics.

Breeders leverage LD mapping to identify which traits will co-inherit during line development and backcrossing. By recognizing linkage blocks, cultivators can select for desired compound profiles while minimizing genetic hitchhiking of unwanted phenotypes.
