"Based on genome-wide SNP arrays and whole-genome sequences, it has been determined that the Romani people carry approximately 20–35% South Asian ancestry [4,7], and North-West India constitutes the major source of this component [4,7,54][...] In general, Romani people carry approximately 65–80% West Eurasian (European, Middle Eastern and Caucasian) ancestry, estimated to have been acquired by extensive gene flow."
