title: Multivariate analysis of head measurements in Punjabi families.
abstract: Four head measurements (head length, head breadth, frontal breadth and head height) have been compared in relatives of different degrees from samples of 200 Punjabi and 125 Belgian families. A method of generalized distances is used which allows examination of the proportions of the head as a whole. The values of the generalized distances between concordant and discordant twins are compared with those between brothers, sisters, siblings, parents-and-children, and parents. The results strongly support the influence of genetic factors, but also demonstrate environmental influence.
