本研究的目的是比较头影测量的水平和垂直距离的遗传性。所用材料包括56对年龄在13-20岁之间的同性别双胞胎。根据通径分析方法确定遗传力（h2）和文化遗传力（c2），并比较遗传标准差与环境标准差的相关性。水平和垂直测量之间没有发现系统差异，但在四个垂直变量中获得最高的遗传力值。
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.
