Description |
Twin studies are often used to study the relative importance of nature versus nurture. BCS70 did not have particularly reliable information about zygosity (whether twins are genetically identical), which made it difficult to conduct this type of research with the information collected from BCS70 twins. As such, in 2008, a postal questionnaire was sent to all pairs of twins with a series of questions to allow zygosity to be accurately identified. The study was undertaken as a part of the project The Relative Importance of Nature, Nurture, and Peer Effects on Adult Outcomes, funded by the Economic and Social Research Council. The aims and objectives of the project were:
This questionnaire was developed based on existing instruments used by other twin studies, and covers self-reported zygosity, physical similarity, and widely used ‘peas-in-a-pod’ questions. A dataset was created from the collected questionnaires, containing three new measures of zygosity. |
