Association of Handedness and Birth Order in Monozygotic Twins
Published online by Cambridge University Press: 01 August 2014
Abstract
In a random sample of 104 pairs of middle-class Caucasian, handedness-discordant twins six years of age or older, a significant relationship has been found between birth order and handedness in monozygotic twins, there being an excess of left-handed among first-born twins (P < 0.01). No such relation has been found in dizygotic twins.
