Occlusion and Arch Size in FamiliesA Principal Components Analysis
Abstract
A statistical analysis of the heritability of seventeen attributes of arch size, arch shape and occlusal relations indicates a dominance of environmental over genetic factors. Some combinations of traits show noticeable genetic influence, while individual occlusal traits appear to be almost entirely related to environmental effects.
