genotyped them for Y chromosome and mitochondrial (mt) DNA markers. They found that a Y-chromosome haplogroup that is found in Asian populations, but not in Europeans, was present in all 14

Romani groups and in 44.8% of the Romani sampled. Similarly, a mtDNA haplogroup that is rare in Europeans but common in Asians was present in all 14 populations and in 26.5% of the sample.

The authors also found dramatic differences in the frequencies of these major haplogroups and other minor ones — those common to European and Middle Eastern populations — among the Romani

men. However, these differences did not correlate with a group's present geographical location or social organization, only with its language and migration history in Europe, indicating

that migration, admixture, marriage within the group and genetic drift have had the strongest hand in shaping these populations. Additionally, low haplogroup diversity among the Roma

strongly indicates that this population has been through a profound bottleneck. This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your
