What uses have scientists found for linkage disequilibrium? Areas of linkage disequilibrium indicate to scientists which sequence was deleted when a mutation occurred in a gene. Linkage disequilibrium can show scientists a gene’s location if known genetic markers correlate with a phenotype. Linkage disequilibrium allows scientists to offer inexpensive tests for inherited risks for certain
