Quizplus · Accepted Answer

Twin studies consistently show a higher concordance for eating disorders in monozygotic (MZ) twins compared to dizygotic (DZ) twins, indicating genetic factors play a role in the development of these disorders. Environmental factors may also contribute, but they are not found to be of greater influence than genetics. Some genes have also been found to affect personality traits associated with eating disorders such as impulsivity and anxiety, suggesting genetics may impact multiple aspects of these disorders.
