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.
The Minnesota Study of Twins Reared Apart was a twin study conducted at the University of Minnesota, independent of the Minnesota Center for Twin and Family Research. In 1979, Thomas J. Bouchard began to study twins who were separated at birth and reared in different families.
Twin studies are utilized in an attempt to determine how much of a particular trait is attributable to either genetics or environmental influence. These studies compare monozygotic and dizygotic twins for medical, genetic, or psychological characteristics to try to isolate genetic influence from epigenetic and environmental influence.
A twin study compares the concordance rate of identical twins to that of fraternal twins. This can help suggest whether a disease or a certain trait has a genetic cause. [3] Controversial uses of twin data have looked at concordance rates for homosexuality and intelligence. Other studies have involved looking at the genetic and environmental ...
Identical Strangers: A Memoir of Twins Separated and Reunited is a 2007 memoir written by identical twins Elyse Schein and Paula Bernstein and published by Random House. [1] The authors, born in New York City in 1968 to Leda Witt, daughter of Nathan Witt , were separated as infants, in part, to participate in a " nature versus nurture " twin ...

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.
Identical twin studies are a useful mechanism for assessing the role of genes and environment. Twin studies have also found that among twins with differing sexual orientations, homosexual twins were significantly more gender nonconforming than their heterosexual co-twin, and that this was noticeable from a young age.
