Because MZ twins carry identical genes, they have been used extensively in medical and psychological research. By comparing sets of MZ twins to carefully matched control sets of DZ twins (the "twin method"), researchers have attempted to elucidate the relative importance of heredity versus environment in the development of certain diseases, in the formation of the personality, and in intelligence.

Some of Our Findings
Here are a few interesting things that the University of Minnesota's Twin Researchers have found out over the years.
- Brain responses (p300) in twins
- As twins grow older, do they become less similar to one another?
- Could Divorce be inherited?
