Answer to Question 2

Monozygotic twins are identical in their genetic endowment, whereas dizygotic twins share as much of their genetics as non-twin siblings do. This difference allows researchers to tease apart the relative contributions of genetics and environment for a variety of different traits and behaviors, such as temperament, intelligence, personality, and so forth. When monozygotic twins have very different characteristics, there is a greater likelihood that genetics are not involved or at least are less involved in the development process. It is not always possible to determine whether something is genetically determined, however, since monozygotic twins often are treated in very similar ways since they appear to be so similar.
