MTFS is a twin study established in June 1989 with 1300 same-gendered twin pairs age 11 or 17, with an additional cohort of 500 such pairs recruited around 2004. Twins were born between 1972 and 2000. [1] All twins born in Minnesota at that time were eligible to participate using birth registry data.
Twin studies are studies conducted on identical or fraternal twins. They aim to reveal the importance of environmental and genetic influences for traits, phenotypes , and disorders. Twin research is considered a key tool in behavioral genetics and in related fields, from biology to psychology.
Thomas J. Bouchard Jr. (born October 3, 1937) is an American psychologist known for his behavioral genetics studies of twins raised apart. He is professor emeritus of psychology and director of the Minnesota Center for Twin and Adoption Research at the University of Minnesota.
The Twins Early Development Study (TEDS) is an ongoing longitudinal twin study based at King's College London.The main goal of TEDS is to use behavioural genetic methods to find out how nature and nurture (environments) can explain why people differ with respect to their cognitive abilities, learning abilities and behaviours.

[2] [3] This hypothesized effect was first proposed by Sandra Scarr, who found support for it in a 1971 study of twins in Philadelphia, and these results were replicated by David C. Rowe in 1999. [ 4 ] [ 5 ] Since then, similar results have been replicated numerous times, though not all replication studies have yielded positive results.
In a large study of five- and six-year-old children, she found that identical twins were similar to fraternal twins and matched pairs of non-twin siblings in almost all of the measured variables. [7] In 1966, Koch authored a book based on her work, Twins and Twin Relations. [8]
From twin studies is typically estimated at 0 because the correlation between monozygotic twins is at least twice the correlation for dizygotic twins. When using the Falconer variance decomposition ( 1.0 = a 2 + c 2 + e 2 {\displaystyle 1.0=a^{2}+c^{2}+e^{2}} ) this difference between monozygotic and dizygotic twin similarity results in an ...
