Linkage Analysis

Linkage analysis is a genetic mapping technique used to identify the physical and genetic distance between markers or traits on a chromosome. In cannabis breeding, this method helps breeders understand how traits are inherited together and determine whether genes are located close to each other on the same chromosome. By tracking inheritance patterns across generations, breeders can map relationships between observable traits (phenotypes) and their underlying genetic markers. Linkage analysis has become increasingly relevant as genomic tools have improved, enabling more precise breeding decisions and trait stacking.

Breeders use linkage analysis to accelerate selective breeding by identifying which traits consistently segregate together. Understanding linkage allows breeders to avoid breeding away desirable characteristics and to more efficiently combine multiple desired traits in a single cultivar.
