Description	Twin studies are often used to study the relative importance of nature versus nurture. NCDS 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 NCDS twins. As such, in 2008, a questionnaire was sent to all pairs of twins which asked a series of questions to allow zygosity to be accurately identified.
