Abstract
The paper is aimed at decomposition the continuously varying phenotype into components due to transmissible and
nontransmissible factors. The linear causal model (path analysis) was applied to incorporate the contribution of environmental
sources of variation (described in terms of indices of socioeconomic status) to familial resemblance on physique
(height and weight) in 342 nuclear families. Parameters of the causal model were estimated according to the TAU transmission
model of Rice, Cloninger, Reich [1978] and linear constraints placed upon the parameters were tested. The
proportion of total phenotypic variance accounted for by genetic and environmental transmissible factors was estimated to
be 62% for height and 3 8% for weight
