Abstract

Little is known about the heritability of most measurements of the orbital region in humans, although they have long been used by anthropologists, medical geneticists, clinicians, and surgeons to describe biometrically normal populations and individuals exhibiting abnormalities of the orbital region (Romanus 1953; Johr 1953; Kerwood et al. 1954; Gerald and Silverman 1965; Laestadius et al. 1969; Pryor 1969; Raposo-do-Amaral 1981; and others). The knowledge of the relative importance of genetic mechanisms on the variability of these measurements may be helpful in understanding intra- and interpopulation characterization and, more optimistically, in uncovering major genetic factors that act on skeletal growth and development.

In this paper we intend to contribute to the understanding of relative influence of genetic and environmental factors on the most important quantitative orbital traits.
