The methods for path analysis of family resemblance (Rao et al., '74) are employed to test hypotheses concerning the inheritance of a‐b, b‐c and c‐d palmar ridge counts using the correlation data of Pateria ('74). Homogeneity chi‐square tests of the various familial correlations provide no evidence for sex‐linkage of either kind, and also suggest that maternal effects are absent. The path coefficient model employed here involves heritability (additive) and common sibling environment. Variance components show that both heritability and common environment are significant, and account for most of the variation at each of the three ridge count areas; b‐c has the highest heritability, significantly higher than that for a‐b or c‐d.
