Abstract
The aim of the present study was to compare horizontal and vertical cephalometric distances with regard to heritability. The material used consisted of 56 pairs of twins of the same sex ranging from 13–20 years of age. Heritability (h2) and cultural inheritance (c2) were determined according to the path analysis method and quotients between genetic and environmental standard deviations were compared. No systematic difference could be found between horizontal and vertical measurements, but the highest heritability values were obtained among four vertical variables.Keywords
