However, the exact parental population group and time of the out-of-India dispersal have remained disputed. In the absence of archaeological records and with only scanty historical documentation of the Roma, comparative linguistic studies were the first to identify their Indian origin. Recently, molecular studies on the basis of disease-causing mutations and haploid DNA markers (i.e. mtDNA and Y-chromosome) supported the linguistic view. The presence of Indianspecific Y-chromosome haplogroup H1a1a-M82 and mtDNA haplogroups M5a1, M18 and M35b among Roma has corroborated that their South Asian origins and later admixture with Near Eastern and European populations. However, previous studies have left unanswered questions about the exact parental population groups in South Asia. Here we present a detailed phylogeographical study of Y-chromosomal haplogroup H1a1a-M82 in a data set of more than 10,000 global samples to discern a more precise ancestral source of European Romani populations. The phylogeographical patterns and diversity estimates indicate an early origin of this haplogroup in the Indian subcontinent and its further expansion to other regions. Tellingly, the short tandem repeat (STR) based network of H1a1a-M82 lineages displayed the closest connection of Romani haplotypes with the traditional scheduled caste and scheduled tribe population groups of northwestern India. | Publication Type: | Journal Article | Source of Publication: | PLoS One, 7(11), p. 1-7 | Publisher: | Public Library of Science | Place of Publication: | United States of America | ISSN: | 1932-6203 | Fields of Research (FoR) 2008: | 219999 History and Archaeology not elsewhere classified | Fields of Research (FoR) 2020: | 439999 Other history, heritage and archaeology not elsewhere classified | Socio-Economic Objective (SEO) 2008: | 950305 Conserving Natural Heritage | Socio-Economic Objective (SEO) 2020: | 130404 Conserving natural heritage | Peer Reviewed: | Yes | HERDC Category Description: | C1 Refereed Article in a Scholarly Journal |
