Question

Quizplus · Accepted Answer

Genetic linkage analysis can be used to determine the location of the gene that causes a disorder, by identifying patterns of inheritance and the relationship between genes on the same chromosome. It cannot determine whether a disorder is caused by genetic factors on its own, and cannot be used to determine whether a disorder actually runs in a family. Linking genes cannot cure a disorder, but can help identify potential targets for therapy or genetic counseling.
