Table 5 Regression results of fluctuating asymmetry (FA) on morphological integration (Evstv) in both components of the shape, for the total sample and subsamples (Native American, European, Admixed/Heterozygous, Homozygous). R2, root mean square error, correlation, degree of freedom, sum squares, mean squares, F value and p value are presented. The bold represent the unique test with statistical significance with α = 0.05. Italic indicate the higher correlations.
