The distribution of ABO blood groups and Rh(D) factor has been studied among the four endogamous groups (Balmiki, Dhanak, Ravidasia and Ramdasia) of Scheduled Caste population of Punjab. The percentage frequencies of O, A, B and AB groups in the combined data were found to be 31.22, 21.91, 37.57 and 9.30, respectively. The Rh negative incidence was recorded as 2.70%. The distribution of these blood genetic markers is well within the ranges observed for other Schedule Caste populations.
