Abstract
In the course of the East Flanders Prospective Twin Survey (EFPTS), ha ndedness was assessed as part of a genealogical study (Meulemans et al ., 1995) in 1616 twins (808 twin pairs) aged 6 to 28. Our findings are that, in this large population-based study with known placentation an d zygosity, the often observed higher frequency of left-handedness in twins is confirmed, that it appears to he independent of zygosity and chorion type, and that the belief that discordant handedness in monozy gotic twins represents mirror-imaging is mythical.
