Multilocus comparison between Romani populations from different European countries, autochthonous European populations and populations from north India The polymorphic systems included in the analysis comprised A₁A₂BO, MN, haptoglobin and Rh (CDE), with a total of 11 independent alleles. Information on these markers was available for the Roma in Slovakia (n = 350) [26], Hungary (n = 507) [11], England (n = 109) [23], Slovenia (n = 350) [27], Sweden (n = 115) [24] and Wales (n = 84) [22], for non-Roma Europeans (n = 5169) and for two north Indian populations, Rajput (n = 175) [34,35] and Punjabi (n = 140) [35,36]. Genetic distances between pairs of populations were computed by means of Reynold's coancenstry coefficient [84] and displayed as a neighbour-joining tree [85]. The robustness of the branches in the tree was assessed with a bootstrap approach [86]. The analysis was conducted using the PHYLIP 3.57c package [87].
