"WebGenetic mapping was practiced for nearly four decades prior to the demonstration that DNA was the hereditary molecule, taking advantage of the phenomenon of "genetic linkage" explained by Morgan using "visible markers." A visible marker is simply a mutation in a particular gene, which imparts a discrete, easily-identified phenotype to an organism. " - How is linkage used in preparing genetic maps
