  • Title: Association of handedness and birth order in monozygotic twins.
    Author: Christian JC, Hunter DS, Evans MM, Standeford FM.
    Journal: Acta Genet Med Gemellol (Roma); 1979; 28(1):67-8. PubMed ID: 575696.
    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 less than 0.01). No such relation has been found in dizygotic twins.
