Linkage Drag
Linkage drag is a genetic phenomenon rather than a terpene itself, but it's frequently discussed in cannabis breeding contexts when discussing terpene inheritance. It describes the co-inheritance of undesired traits alongside desired ones due to physical proximity on a chromosome. In cannabis breeding, linkage drag can occur when a breeder selects for a specific terpene profile or cannabinoid ratio, but unintentionally carries along neighboring genes that produce unfavorable characteristics—such as reduced vigor, altered growth patterns, or undesired secondary aromas. Understanding linkage drag is essential for breeders working to stabilize strains without losing desirable genetic expressions over multiple generations.

Breeders working with linkage drag employ backcrossing and test-crossing strategies to separate desired traits from unwanted ones inherited due to chromosomal proximity. Mapping and marker-assisted selection are increasingly used to identify and break unfavorable linkages while preserving target terpene profiles.
