How would the use of a large series of monozygotic and dizygotic twins enhance studies on the genetic basis of human behavior?

Monozygotic twins are genetically identical, and when reared under the same versus different environments, one can estimate the degree to which variation in behavior is determined by heredity. Dizygotic twins are genetically different but by having the same intrauterine and developing environment (if reared in the same household), one can again estimate the influence of heredity on behavioral traits.
