Variations in asymmetry and interdigital diversity for the three finger‐dermatoglyphic traits, total finger ridge count (TRC), absolute total finger ridge count (ARC), and finger pattern intensity index (PII) have been studied here from a sample of 646 males belonging to nine population groups from Maharashtra, India. It is seen that at such local level of population differentiation the ridge count measures TRC and ARC discriminate the population better as compared to PII. A considerable amount of variations also exist in their asymmetries and interdigital diversities and these suggest the possibility of their genetic controls. Such genetic controls might mediate both asymmetry and interdigital diversity jointly, as there seems to be positive correlation between these measures with respect to all the three finger‐dermatoglyphic traits.
