Abstract

In the course of the East Flanders Prospective Twin Survey (EFPTS), handedness 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 and zygosity, the often observed higher frequency of left-handedness in twins is confirmed, that it appears to be independent of zygosity and chorion type, and that the belief that discordant handedness in monozygotic twins represents mirror-imaging is mythical.

摘要

在东佛兰德前瞻性双胞胎调查（EFPTS）过程中，作为一项系谱研究的一部分（Meulemans等人，1995年），对1616名6至28岁的双胞胎（808对双胞胎）的用手习惯进行了评估。我们的研究结果是，在这项基于大量人群且已知胎盘形成和受精卵性别的研究中，经常观察到的双胞胎中左利手频率较高的现象得到了证实，它似乎与受精卵性别和绒毛膜类型无关，而且认为同卵双胞胎中不一致的用手习惯代表镜像的观点是虚构的。
