Abstract:
Fluctuating asymmetry for the digital quantitative value was analyzed in a sample of twins (mono and dizygotic) and singletons. The aim was to check if the influence of twinning on the development is expressed in a higher fluctuating asymmetry in twins than in singletons. The results have shown that significant differences exist among the three groups studied, and these differences are fundamentally expressed when the radial and ulnar counts are considered separately.
