UM1 = first maxillary molar; hy = hypocone area; ma = metacone area; pa = paracone area; pr = protocone area; ns = not significant. Total c² = amount of phenotypic variance attributable to covariates; Total h² = (Residual h²)(1-Total c²); Total e² = [1-(Total c² + Total h²)]; Coefficient of variation (CV) = [standard deviation * 100]/mean; measurements are in mm².
