Trait Correlations

Nonmetric traits are frequently analyzed in the field of anthropology to measure genetic relatedness, or biodistance, within or between populations. These studies are performed under the assumption that nonmetric traits are genetically inherited. However, much of the research on nonmetric traits has revealed that numerous factors can confound heritability. Skull size is one of the factors that are shown in some samples to have an effect on the expression of nonmetric traits. There is evidence that nonmetric trait expression is population specific; therefore, the current study was performed to determine if size-trait correlations would occur within a single population. Nonmetric traits in a sample of 20 skulls (South Eastern Asian origin) are analyzed to determine if there are correlations between skull size and expression of nonmetric traits. Intertrait correlations are also examined. This type of study is important because if the expression of certain nonmetric traits is related to factors outside of genetics, then those traits would not be useful in biodistance studies. The results of this study indicate that there are no correlations between overall skull size and nonmetric traits. However, correlations were found between individual measurements and nonmetric traits, as well as between traits.

One hundred dental casts of modern Pima Amerindian children, 50 male and 50 female, wereexamined for the presence and expression of thirteen deciduous nonmetric traits. The effects of sexual dimorphism,asymmetry, and inter-trait association on trait presence were examined to evaluate their utility in populationdistance studies. No statistically significant differences between the sexes were observed. The majority of examinedvariants displayed a strong trend toward bilateral expression and no statistically significant differences betweenantimeres occurred. These data support the hypothesis that strong genetic components coupled with negligibleenvironmental influences are involved in deciduous trait presence. Five statistically significant associations betweenvariants were detected. Four of these involved a combination of incisor and canine shoveling within and betweenjaws. This indicates that their combined use in biological distance studies violates the mathematical assumption ofindependence. The lack of significant sexual dimorphism and asymmetry in the deciduous discrete traits examinedherein supports their use in population distance analyses if precautions are taken to use non-associated traits.
