Discrete dental trait asymmetry was scored on four Mexican Indian and two Afro‐Belizean groups. The Mexican populations show significantly higher mean asymmetry than the two populations from Belize even though the Belizean groups have larger teeth. Point biserial coefficients of correlation between asymmetry of discrete traits and tooth size is low and in most cases not significant. This study indicates that populational and ethnic differences exist in the asymmetry of discrete traits, suggesting that these traits may be used to investigate the etiology of dental asymmetry, and the relative roles of genetics and environment.
