A focused population profile of Indian Bengalis, their eastern Indian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Indian Bengalis are Bengali-speaking communities primarily associated with West Bengal and other Indian parts of the Bengal cultural region.
Bengali is the main language, with regional forms shaped by Kolkata, western Bengal, borderland districts, and links to neighboring Odisha, Assam, Jharkhand, Bihar, and Bangladesh.
As a genetic reference, Bengali India is useful for comparison with Chenchu, Bengali Bangladesh, Indo-Guyanese, Kapu, Relli, Bengali, Odia Khandayat, Indian South, Bengali Bangladesh Brahmanbaria, and Bengali Bangladesh Southeast.
In the World Genetics modern G25 comparison, Bengali India is closest to Chenchu, Bengali Bangladesh, Indo-Guyanese, Kapu, Relli, Bengali, Odia Khandayat, Indian South, Bengali Bangladesh Brahmanbaria, and Bengali Bangladesh Southeast. Because this reference has a small sample size, the result should be read cautiously; it still connects to Bengali Bangladesh and broader South Asian references.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Indian Bengali ancestry is best interpreted in the eastern Indian and Bengali context, with broader South Asian references appearing alongside Bengali Bangladesh and Bengali regional references.
The heatmap should emphasize West Bengal, eastern India, Bangladesh, the Bengal cultural region, Odisha-adjacent areas, and broader South Asian comparison zones.
Yes. Bengali Bangladesh appears among the closest matches, though this Indian Bengali reference has a small sample size.
With a one-sample reference, some broad South Asian neighbors can appear close. The page should be interpreted with Bengali and eastern Indian context.
They are related Bengali-region references, but regional variation and sample size can shift the closest-match list.
