All studies agree that there is a significant relationship between the Sinhalese and the Bengalis and South Indian Tamils, and that there is a significant genetic relationship between Sri Lankan Tamils and Sinhalese. This is also supported by a genetic distance study, which showed low differences in genetic distance between the Sinhalese and the ], ], and ] volunteers. | ||

Origins of the sinhalese
Genetic studies on the Sinhalese is part of population genetics investigating the origins of the Sinhalese population.
All studies agree that there is a significant relationship between the Sinhalese and the Bengalis and South Indian Tamils, and that there is a significant genetic relationship between Sri Lankan Tamils and Sinhalese. This is also supported by a genetic distance study, which showed low differences in genetic distance between the Sinhalese and the Bengali, Tamil, and Keralite volunteers.
Relationship to Bengalis
An Alu polymorphism analysis by Mastana S (2007) using Sinhalese, Tamil, Bengali, Gujarati (Patel), and Punjabi as parental populations found the following proportions of genetic contribution. The Sinhalese sample size used was 121 individuals.:
| Statistical Method | Bengali | Tamil | North Western |
|---|---|---|---|
| Point Estimate | 57.49% | 42.5% | - |
| Maximum Likelihood Method | 88.07% | - | - |
| Using Tamil, Bengali and North West as parental population | 50-66% | 11-30% | 20-23% |
| Parental population | Bengali | Tamil | Gujarati | Punjabi |
|---|---|---|---|---|
| Using Tamil and Bengali as parental population | 70.03% | 29.97% | - | |
| Using Tamil, Bengali and Gujarati as parental population | 71.82% | 16.38% | 11.82% | |
| Using Bengali, Gujarati and Punjabi as parental population | 82.09% | - | 15.39% | 2.52% |
Analysis of X chromosome STRs by Perera et al. (2021) found the Sinhalese (as well as Sri Lankan Tamils and Sri Lankan Muslims) to be more closely related to Bengalis, than to the Indian Tamils of Sri Lanka.
Genetic distance analysis by Kirk (1976) found the Sinhalese to be closer to the Bengal than they are to populations in Gujarat or the Panjab.
D1S80 allele frequency (a popular allele for genetic fingerprinting) is also similar between the Sinhalese and Bengalis, suggesting the two groups are closely related.
The Sinhalese also have similar frequencies of the allele MTHFR 677T (13%) to West Bengalis (17%).
Relationship to Indian Tamils
A genetic admixture study by Kshatriya (1995) found the Sinhalese to have a higher contribution from Indian Tamils (69.86% +/- 0.61), compared with the Bengalis (25.41% +/- 0.51).
Genetic distance analysis by Roychoudhury AK et al. (1985) suggested the Sinhalese are more closely related to South and West Indian populations, than the Bengalis.
Genetic distance analysis by Kirk (1976) suggested the Sinhalese are closer to the Tamils and Keralites of South India, than they are to the populations in Gujarat or the Panjab.
A 2023 study by Singh et al using higher resolution markers than previous studies found that there was higher gene flow from South India to the Sinhalese than from North India, with the Sinhalese sharing the highest Identity by descent with Tamils specially Piramalai Kallars, compared to the other Indian populations studied. The study also found heightened sharing with the Maratha of India , consistent with a West Eurasian contribution .This excess sharing of segments suggests common roots of Sinhala with the Marāṭhā corroborating the linguistic hypothesis of Lazarus Geiger, Ralph Lilley Turner, and George van Driem. The total Sinhalese sample size used was 9 individuals.
Relationship to North West Indians
An Alu polymorphism analysis by Mastana S (2007) found a North West Indian contribution (20-23%).
Analysis of X chromosome STRs by Perera et al., (2011) showed that the Sinhalese, Sri Lankan Tamil, Moor and Indian Tamils of Sri Lanka, share affinities with the Bhil (an Indigenous group) of North West India.
Relationship to other major ethnic groups in Sri Lanka
A study looking at genetic variation of the FUT2 gene in the Sinhalese and Sri Lankan Tamil population, found similar genetic backgrounds for both ethnic groups, with little genetic flow from other neighbouring Asian population groups. Studies have also found no significant difference with regards to blood group, blood genetic markers (Saha, 1988) and single-nucleotide polymorphism between the Sinhalese and other ethnic groups in Sri Lanka. Another study has also found "no significant genetic variation among the major ethnic groups in Sri Lanka". This is further supported by a study which found very similar frequencies of alleles MTHFR 677T, F2 20210A & F5 1691A in Indian Tamil, Sinhalese, Sri Lankan Tamil, and Sri Lankan Moor populations.
Relationship to other South Asians and West Asians
A 1985 study conducted by Roychoudhury AK and Nei M indicating the values of genetic distance showed that the Sinhalese, along with the four Indian subcontinent populations from Punjab, Gujarat, Andhra Pradesh, and Bangladesh, were closer to Afghans and Iranians than the neighboring East/Southeast Asian groups represented by the Bhutanese, Malays, Bataks in northern Sumatra, and the Chinese.
Relationship to East and Southeast Asians
Genetic markers of immunoglobulin among the Sinhalese show high frequencies of afb1b3 which has its origins in the Yunnan and Guangxi provinces of southern China. It is also found at high frequencies among Odias, certain Nepali and Northeast Indian, southern Han Chinese, Southeast Asian and certain Austronesian populations of the Pacific Islands. At a lower frequency, ab3st is also found among the Sinhalese and is generally found at higher frequencies among northern Han Chinese, Tibetan, Mongolian, Korean and Japanese populations. The Transferrin TF*Dchi allele which is common among East Asian and Native American populations is also found among the Sinhalese. HumDN1*4 and HumDN1*5 are the predominant DNase I genes among the Sinhalese and are also the predominant genes among southern Chinese ethnic groups and the Tamang people of Nepal. A 1988 study conducted by N. Saha, showed the high GC*1F and low GC*1S frequencies among the Sinhalese are comparable to those of the Chinese, Japanese, Koreans, Thais, Malays, Vietnamese, Laotians and Tibetans. Hemoglobin E a variant of normal hemoglobin, which originated in and is prevalent among populations in Southeast Asia, is also common among the Sinhalese and can reach up to 40% in Sri Lanka.
Paternal Line
Y-DNA of Sinhalese
Kivisild et al.(2003) found the most common Y-chromosome DNA haplogroups found in the Sinhalese are Haplogroup R2, Haplogroup L, Haplogroup R1a and F in that order.
| Population | n | C | E | F | G | H | I | J | K | L | N | O | P | Q | R | R1 | R1a | R1b | R2 | T | Others | Reference |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Sinhalese | 39 | 0 | 0 | 10.3% | 0 | 10.3% | 0 | 10.3% | 0 | 18% | 0 | 0 | 0 | 0 | 0 | 0 | 12.8% | 0 | 38.5% | 0 | Kivisild2003 |
Maternal Line
MtDNA of Sinhalese
Ranweera et al. (2014) found the most common mtDNA haplogroup in the Sinhalese to be, Haplogroup M and Haplogroup U (U7a) , Haplogroup R (r30) and Haplogroup G (G3a1′2).
Haplogroup M represents the dispersal of modern humans around 60.000 years ago along the southern Asian coastline following a southern coastal route across Arabia and India to reach Australia short after.
Haplogroup U7 is considered a West Eurasian–specific mtDNA haplogroup, believed to have originated in the Black Sea area approximately 30,000 years ago. In South Asia, U7 occurs in about 12% in Gujarat, while for the whole of India its frequency stays around 2%, and 5% in Pakistan. In the Vedda people of Sri Lanka it reaches its highest frequency of 13.33% (subclade U7a). It is speculated that large-scale immigration carried these mitochondrial haplogroups into India.
Chaubey states that "considerable number of maternal lineages of Sri Lanka is shared with India, more precisely with southern part of India."
