Interpopulation variation in fluctuating asymmetry of the palmar A-B ridge-count

摘要: Fluctuating asymmetry was measured by the Pearson correlation coefficient between a-b ridge-counts of right and left hands. Such data were available for 38 samples, which grouped major geographical regions. Significant heterogeneity exists within some groups but group component is highly significant in both sexes. Our results show that a sizable fraction variation fluctuating related to race. There no evidence it follows environmental or ecological lines. The races suggests there genetic magnitude asymmetry.
