Study
MTFS was established in June 1989 using same-gendered twin pairs age 11 or 17. All twins born in MN at that time were invited to participate using birth registry data. 500 additional 11 year old twin-pairs were added in 2000. Twin studies are valuable to researchers because identical twins share 100% of their genes and fraternal twins share, on average, 50% of their genes. Both identical and fraternal twins share certain aspects of their environment (e.g. religious practices in the home). This allows researchers to estimate the heritability of certain traits. Participants are asked about academic ability, personality, and interests; family and social relationships; mental and physical health; physiological measurements. Of interest to researchers are prevalence of psychopathology, substance abuse, divorce, leadership, and other traits and behaviors related to mental and physical health, relationships, and religiosity.

Famous quotes containing the word study:
“Why should I seek for love or study it?
It is of God and passes human wit;
I study hatred with great diligence,
For that’s a passion in my own control,
A sort of besom that can clear the soul
Of everything that is not mind or sense.”
—William Butler Yeats (1865–1939)
“Daniel as a lad bought a handkerchief on which the Federal Constitution was printed; it is said that at intervals while working in the meadows around this house, he would retire to the shade of the elms and study the Constitution from his handkerchief.”
—For the State of New Hampshire, U.S. public relief program (1935-1943)
“It’s worth living abroad to study up on genteel and delicate manners. The maid smiles continuously; she smiles like a duchess on a stage, while at the same time it is clear from her face that she is exhausted from overwork.”
—Anton Pavlovich Chekhov (1860–1904)
