There are a few genetic studies on Roma Origins in India. One study concluded that proto-Romani had a Southindian paternal lineage contributor (Reguiro) I quote The Romani have been described as a conglomerate of genetically isolated founder populations . Their demographic history provides a good explanation for the high incidence of several rare genetic Mendelian disorders and private mutations compared to other neighboring European populations . Molecular anthropological studies have provided new relevant insight into the demographic history of this population. Thus, analyses of the Y-chromosome and mtDNA have revealed the existence of interesting genetic features in the Romani â€“. Kalaydjieva et al.  analyzed three groups of Vlax Roma from Bulgaria and identified a close mtDNA and Y-chromosome resemblance between these groups, most likely indicating a common and recent origin. Gresham et al.  analyzed the Romani population mainly residing in Bulgaria and reported a high frequency of the Y-chromosome lineages defined by a mutation in the locus M82 (identifying the Indian specific Y-chromosome haplogroup H1a1a-M82). They also observed a high frequency of the Asian mtDNA macro-haplogroup M with little genetic variation within these populations; according to these authors, this pattern would be consistent with a small group of founders splitting from a single ethnic population most likely located in the Indian subcontinent. In a follow-up study , new aspects of the Vlax Roma were revealed, such as the existence of recent splits occurring after their arrival in Europe, asymmetric migration flows for males and unequal growth rates. Malyarchuk et al.  analyzed the control region segment of a sample of Polish Roma, and the mitogenome of a Polish donor carrying a M5 Roma lineage; their study also indicated the existence of mtDNA founder effects in the Polish Roma. Over the last few years, other Romani populations have been analyzed, including individuals from Hungary, Romania, Slovakia and Poland     . Regarding uniparental markers, a recent Y-chromosome study by Regueiro et al.  claims that the Roma descended from southern Indian populations, thereby contradicting various reports based on mtDNA and autosomal studies (see below) that pointed to northwest India as the homeland of proto-Romani. The most recent genome-wide SNP study on European Romani by Mendizabal et al.  indicated that their diaspora occurred from a single initial founder population from North/northwest India ~1.5 thousand years ago (kya), followed by a rapid migration through the Near or Middle East, and then, about 0.9 kya, through the Balkans to Western Europe. Almost at the same time, Moorjani et al.  analyzed genome-wide SNPs from 27 Roma samples belonging to six European groups; their data indicate an 80% Western European ancestry and that the admixture of South Asian and European ancestry occurred about 0.85 kya. PLOS ONE: Indian Signatures in the Westernmost Edge of the European Romani Diaspora: New Insight from Mitogenomes here is the most recent genome wide study Reconstructing the Population History of European Romani from Genome-wide Data romanis are most probably meghawal/kashmiri pandits from northwest india autosomally and maternally, ydna revealed untouchable ancestry from northwestindia (meghawal are also untouchables but are from northwestindia and genetically similar to brahmins and rajputs etc.) kashmiri pandits are brahmins. only one study found that roma ydna haplotype is similar to southindians, it could be outlier study, or somewhere in the distant past a group of southindian males married northwest indian females and created the romani. the most recent study founds roma to be 47% of the ancestral population (using meghawal as a proxy). that means they are half northwest indian half european, caucasus, central asia, near east etc.
