    Abstract:
    OBJECTIVES: Studies indicate the complex nature of the genetic structure of the European Roma which has been shaped by different effects of their demographic history, while preserving their ancestral Indian origin. The primary aims of this study were to present for the first time the paternal profiles of the Roma from Bosnia and Herzegovina based on the data from Y-chromosome STR loci, identify the components of non-Roma paternal gene flow into the Roma, and evaluate the genetic relationships with other European Roma populations. MATERIALS AND METHODS: In this study, 110 DNA samples of unrelated males from Roma populations residing in different regions of Bosnia and Herzegovina were genotyped using the 23 Y-STR loci included in the PowerPlex Y23 system. RESULTS: The analysis of the genetic structure of the Bosnian-Herzegovinian Roma revealed intra-country population substructuring and indicated differing genetic affinities between the Bosnian-Herzegovinian Roma and other European Roma populations. The paternal genetic structure of the Bosnian-Herzegovinian Roma has two components: an ancestral component represented by haplogroup H1a1a-M82, and European component presented by haplogroups I1-M253, I2a1a2b-L621, J2a1a-L26, J2a1a1a2b2a3~Z7671, J2b2a-M241, G2a2b2a1a1b-L497, and E1b1b-M215. CONCLUSION: Genetic relations between the Bosnian-Herzegovinian Roma and other European Roma are shaped by different influences on their demographic history. The data suggest that the paternal gene pool of the Roma from Bosnia and Herzegovina might be a consequence of an early separation of the proto-Roma population and the later gene flow as well as factors of the isolation that accompany the Roma populations in some Bosnian-Herzegovinian regions.
