根据书面资料，罗姆人（吉普赛人）大约在1,000年前从印度来到巴尔干半岛，随后传遍欧洲的几个地区。遗传数据，特别是来自Y染色体的数据，已经支持了这个模型，并且可以潜在地完善它。我们现在提供了来自五个罗姆人和两个非罗姆人群体（N = 787）的Y染色体标记的分析，以调查罗姆人群体之间的遗传相关性，并进一步了解他们可能的印度起源，非罗姆男性对罗姆人口的遗传贡献，以及他们在欧洲分裂和迁移的早期历史。罗姆人父系基因库的两个主要来源被确定为南亚和欧洲。所有罗姆人群体中H1 a-M82谱系的多样性减少和扩展意味着来自印度次大陆单一父系祖先的共同血统。罗马父系基因库还包含E1 b1 b1 a-M78和J2 a2-M67谱系的特定子集，这意味着在巴尔干半岛的早期定居以及随后涌入喀尔巴阡盆地期间的混合物。在典型的欧洲单倍群I1-M253、I2 a-P37.2、I2 b-M223、R1 b1-P25和R1 a1-M198的低和中等频率中明显的额外混合物以更种群特异性的方式发生。美国物理人类学杂志145：21-29，2011.

According to written sources, Roma (Romanies, Gypsies) arrived in the Balkans around 1,000 years ago from India and have subsequently spread through several parts of Europe. Genetic data, particularly from the Y chromosome, have supported this model, and can potentially refine it. We now provide an analysis of Y-chromosomal markers from five Roma and two non-Roma populations (N = 787) in order to investigate the genetic relatedness of the Roma population groups to one another, and to gain further understanding of their likely Indian origins, the genetic contribution of non-Roma males to the Roma populations, and the early history of their splits and migrations in Europe. The two main sources of the Roma paternal gene pool were identified as South Asian and European. The reduced diversity and expansion of H1a-M82 lineages in all Roma groups imply shared descent from a single paternal ancestor in the Indian subcontinent. The Roma paternal gene pool also contains a specific subset of E1b1b1a-M78 and J2a2-M67 lineages, implying admixture during early settlement in the Balkans and the subsequent influx into the Carpathian Basin. Additional admixture, evident in the low and moderate frequencies of typical European haplogroups I1-M253, I2a-P37.2, I2b-M223, R1b1-P25, and R1a1-M198, has occurred in a more population-specific manner.
