Palmar dermatoglyphics of the scheduled caste Madigas in Andhra Pradesh

The study reports on bilateral palm prints among 400 unrelated individuals (200 males and 200 females) of Madigas in two revenue districts of Cuddapah and Chittoor in Andhra Pradesh were collected and analysed. The principal mainline formula is frequently occurring modal type in either sex. The highest incidences of Mainline D, Mainline C, Mainline B and Mainline A endings were commonly observed in types 11, 91 7 and 3 respectively. Majority of the individuals possess axial triradius at t irrespective of sex difference. A general trend of the prevalence of the true patterns in decreasing order can be seen as IV inter-digital area > III interdigital area > hypothenar area > thenar/I interdigital area > II interdigital area. The above values of the present study compared to other populations reveal the values are within the range of AP caste populations.
