متن کاملTwin Studies: Software and Algorithms
In 1865, Sir Francis Galton (1822–1911) formally described the differences between identical (monozygotic, MZ) and fraternal (dizygotic, DZ) twins, and suggested that MZ twins were genetically identical (Galton, 1865). This distinction yields a natural experiment, because comparison of the similarity of these two types yields information about the relative importance of heredity versus environm...
متن کاملRecruitment and attrition in twin register studies of childhood behavior: the example of the Australian Twin ADHD Project.
There are a growing number of large-scale initiatives for twin registers of children. The Australian Twin ADHD Project (ATAP) is used to illustrate two key limitations which may arise with such studies, namely (1) the importance of including or possibly excluding families in which one or both twins have significant developmental disability, and (2) the selective failure to recruit and/or the se...
متن کاملGenetic and environmental influences on antisocial behavior: a meta-analysis of twin and adoption studies.
A meta-analysis of 51 twin and adoption studies was conducted to estimate the magnitude of genetic and environmental influences on antisocial behavior. The best fitting model included moderate proportions of variance due to additive genetic influences (.32), nonadditive genetic influences (.09), shared environmental influences (.16), and nonshared environmental influences (.43). The magnitude o...
متن کاملDesign and implementation of a twin-family database for behavior genetics and genomics studies.
In this article we describe the design and implementation of a database for extended twin families. The database does not focus on probands or on index twins, as this approach becomes problematic when larger multigenerational families are included, when more than one set of multiples is present within a family, or when families turn out to be part of a larger pedigree. Instead, we present an al...
