A focused population profile of Sri Lankan Tamils, their island South Asian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Sri Lankan Tamils are a Tamil-speaking population of Sri Lanka, especially associated with the Northern and Eastern provinces, Jaffna, Trincomalee, Batticaloa, and diaspora communities worldwide. They are distinct from, but related to, Tamil-speaking populations in South India.
Tamil is a Dravidian language with a long literary history and major communities in both Sri Lanka and Tamil Nadu. Sri Lankan Tamil varieties have their own regional features and community histories.
As a genetic reference, Tamil Sri Lanka should be compared with Sri Lankan, Sinhalese, Telugu, South Indian, and Tamil or Dravidian-speaking references.
In the World Genetics modern G25 comparison, the closest non-self match for Tamil Sri Lanka is Sri Lankan. Other nearby references include Telugu Naidu Andhra Pradesh, Tamil Yadav Pondicherry, Tamil Mukkulathor Kallar, and Sinhalese. This gives the Tamil Sri Lanka profile its nearest modern genetic context inside the current reference database.

The ancestry model gives deeper component proportions, while closest matches show modern similarity. Sri Lankan Tamil results are best interpreted as island South Asian with strong links to Sri Lankan and South Indian references.
The heatmap should emphasize Sri Lanka, Tamil Nadu, southern India, and nearby South Asian reference zones.
The closest non-self match in this World Genetics comparison is Sri Lankan. Other nearby references include Telugu Naidu Andhra Pradesh, Tamil Yadav Pondicherry, Tamil Mukkulathor Kallar, and Sinhalese.
In the current modern G25 reference set, Sri Lankan is the closest listed match to the Tamil Sri Lanka average after removing Tamil Sri Lanka itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Tamil Sri Lanka G25 average, giving the closest-match results a geographic view.
