Michigan Twins Project
The Michigan Twins Project (MTP) is an on-going, population-based study of roughly 20,000 same-sex male, same-sex female, and opposite sex twins between the ages of 3 and 25 years old. The primary purpose of this study is to investigate genetic and environmental influences on a range of physical and mental health variables, as well as to compile a database of twin families in Michigan interested in participating in future twin research.

Famous quotes containing the words twins and/or project:
“What if there are not only two nostrils, two eyes, two lobes, and so forth, but two psyches as well, and they are separately equipped? They go through life like Siamese twins inside one person.... They can be just a little different, like identical twins, or they can be vastly different, like good and evil.”
—Norman Mailer (b. 1923)
“The trenchant editorials plus the keen rivalry natural to extremely partisan papers made it necessary for the editors to be expert pugilists and duelists as well as journalists. An editor made no assertion that he could not defend with fists or firearms.”
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
