Many sample studies therefore carry information on the incidence of R1a and/or its subclassifications, in particular the dominant branching line represented by the haplogroups R1a1 and R1a1a. The table below collates information from a number of such sample studies, with incidence frequencies in sample data reported as percentages, along with ...

The spread of R1a1 in Indian subcontinent is associated with Indo-Aryan migrations into the region from South Central Asia that occurred around 3,500-4,000 years before present. The R1a-Z93 paternal genetic in Romani people was also discovered. [ 10 ]

The conclusion that R1a originated in India has been questioned by more recent research, [20] [40] [note 7] offering proof that R1a arrived in India with multiple waves of migration. [20] [41]

One of the major factors that has still kept the origin of the Indian caste system obscure is the unresolved question of the origin of Y-haplogroup R1a1*, at times associated with a male-mediated major genetic influx from Central Asia or Eurasia, which has contributed to …

Mar 10, 2025 · Modern Distribution in the Indian Subcontinent: R1a as a whole is one of the dominant Y-haplogroups in India and Pakistan, and most R1a in this region falls within the Z93 branch. It is prevalent among both Indo-European language-speaking and …

In India and Pakistan, R1a ranges from 15 to 50% of the population, depending on the region, ethnic group and caste. R1a is generally stronger is the North-West of the subcontinent, and weakest in the Dravidian-speaking South (Tamil Nadu, Kerala, Karnataka, Andhra Pradesh) and from Bengal eastward.

Three distinct lineages were revealed based upon 13 haplogroups. The first was a Central Asian lineage harbouring haplogroups R1 and R2. The second lineage was of Middle-Eastern origin represented by haplogroups J2*, Shia-specific E1b1b1, and to some extent G* and L*.
