The 2024 research Distinct Positions of Genetic and Oral Histories: Perspectives from India applied qpAdm modeling to find the proportions of Steppe and Onge-related (AASI or the indigenous Indian component) ancestry and '''Bhumihars of Bihar came out to have the highest Steppe ancestry (29.0%) among the Brahmin groups, more than Brahmin Tiwari (27.9%), Saryuparin Brahmins (26.1% Steppe), and West Bengal Brahmins (22.3% Steppe)'''. Their estimated Steppe ancestry was also higher than that of the sampled Rajputs (20.8% Steppe) and Khatris (26.9% Steppe). | The 2024 research Distinct Positions of Genetic and Oral Histories: Perspectives from India applied qpAdm modeling to find the proportions of Steppe and Onge-related (AASI or the indigenous Indian component) ancestry and '''Bhumihars of Bihar came out to have the highest Steppe ancestry (29.0%) among the Brahmin groups, more than Brahmin Tiwari (27.9%), Saryuparin Brahmins (26.1% Steppe), and West Bengal Brahmins (22.3% Steppe)'''.

Conversely, Bhumihars displayed the lowest Onge-related ancestry (20.7%) among the Brahmin groups in the dataset, lower than Brahmin Tiwari (23.4%), Saryupari Brahmins (22.8%), West Bengal Brahmins (30.6%), Rajputs (21.9%) but the Khatris (11.6%) have even lower Onge related ancestry than Bhumihars.
