Genetic studies on Sinhalese

genetic studies on sinhalese people, genetic studies on sinhalese language
Genetic studies on the Sinhalese is part of population genetics investigating the origins of the Sinhalese populations today

Some of the older studies looking at the origin of the Sinhalese erroneously suggest a predominantly Tamil origin followed by a significant Bengali contribution with a slight North Western Indian contribution While modern studies using more sophisticated testing point towards a predominantly Bengali contribution and a minor South Indian Tamil and North Western Indian contribution respectively

All studies agree however, that there is a significant relationship between the Sinhalese and the South Indian Tamils and Bengalis and that there is a significant genetic relationship between Sri Lankan Tamils and Sinhalese, them being closer to each other than other South Asian populations This is also supported by a genetic distance study, which showed low differences in genetic distance between the Sinhalese and the Tamil, Keralite and Bengali volunteers

Predominantly Bengali origin

Genetic26526 admixture of Sinhalese by Dr Saha Papiha

An Alu polymorphism analysis of Sinhalese from Colombo by Dr Sarabjit Mastanain in 2007 using Tamil, Bengali, Gujarati Patel, and Punjabi as parental populations found different proportions of genetic contribution:

Statistical Method Bengali Tamil North Western
Point Estimate 5749% 425% -
Maximum Likelihood Method 8807% - -
Using Tamil, Bengali and North West as parenteral population 50-66% 11-30% 20-23%

A genetic distance analysis by Dr Robet Kirk also concluded that the modern Sinhalese are most closely related to the Bengalis

This is further substantiated by a VNTR study, which found 70-82% of Sinhalese genes to originate from Bengali admixture:

Parenteral population Bengali Tamil Gujarati Punjabi
Using Tamil and Bengali as parenteral population 7003% 2997% -
Using Tamil, Bengali and Gujarati as parenteral population 7182% 1638% 1182%
Using Bengal, Gujarati and Punjabi as parenteral population 8209% - 1539% 252%

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%

A test for Y-chromosome DNA haplogroups conducted by Dr Toomas Kivisild on Sinhalese of Sri Lanka has shown that 23% of the subjects were R1a1a R-SRY1532 positive Also in the same test 241% of the subjects were R2 positive as subclades of Haplogroup P 92R7 Haplogroup R2 is also found in a considerable percentage among Bengalis of India Sample size used was 87 subjects

These findings are compatible with the historical chronicles the Mahavamsa and Dipavamsa Which describe a Vanga prince Prince Vijayafrom Sinhapura in Lata or Lala of being an early settler of Sri Lanka and the progenitor of the Sinhalese The Vangas are generally identified as Bengalis On the other hand, Lata is identified with modern-day Gujarat, and Sinhapura with modern Sihor in the Kathiawar peninsular of Gujarat Furthermore, the Mahawamsa states that Vijaya landed first at Supparaka identified with modern Sopara, in the Thane district of Maharashtra, while the Dipavamsa mentions 'Suppara' and a further intermediate port, Bharukkaccha modern Bharuch, a port in Gujarat, at the mouth of the Narmada Vijaya's grandfather was reputed to be a lion, and lions have not lived in Bengal in historic times, while they have in Gujarat so it was possible that the lion image was borrowed from there

Genetic distance of Sinhalese to other ethnic groups in the Indian Subcontinent according to an Alu Polymorphism analysis Genetic distance of Sinhalese to other ethnic groups

A study in 2007 found similar frequencies of the allele HLA-A02 in sinhalese 74% and North Indian subjects 67% HLA-A02 is a rare allele which has a relatively high frequency in North Indian populations and is considered to be a novel allele among the North Indian population This suggests possible North Indian origin of the Sinhalese

Linguistically the Sinhalese are closer to North Indians than South Indians, as the Sinhala language is a member of the Indo-Aryan languages On the other hand, South Indians speak languages belonging to the Dravidian languages The Sinhalese therefore can trace a connection to their North Indian origins through this Not only this but the Sinhalese predominantly follow Theravada Buddhism and for centuries maintained strong connections with North Eastern India, while it too was predominantly Buddhist This further strengthens the connection of migration between the two well after the believed initial North Indian migration to Sri Lanka

Relationship to other 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 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 South Indian Tamil, Sinhalese, Sri Lankan Tamil and Moor populations

Relationship to East and Southeast Asians

Genetic studies show that the Sinhalese have received some genetic flow from neighboring populations in East Asia and Southeast Asia, such as from the ethnically diverse and disparate Sino-Tibetan-speaking peoples and Austro-Asiatic peoples, which is due to their close genetic links to Northeast India A 1985 study conducted by Roychoudhury AK and Nei M, indicated the values of genetic distance showed that the Sinhalese people were slightly closer to Mongoloid populations due to gene exchange in the past In regards to comparisons of root and canal morphology of Sri Lankan mandibular molars, it showed that they were further away from Mongoloid populations Among haplogroups found in East Asian populations, a lower frequency of East Asian mtDNA haplogroup, G has been found among the populations of Sri Lanka alongside haplogroup D in conjunction with the main mtDNA haplogroup of Sri Lanka's ethnic groups, haplogroup M In regards to Y-DNA, Haplogroup C-M130 is found at low to moderate frequencies in Sri Lanka

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 Bengalis, 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 TFDchi allele which is common among East Asian and Native American populations is also found among the Sinhalese HumDN14 and HumDN15 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 GC1F and low GC1S frequencies among the Sinhalese are comparable to those of the Chinese, Japanese, Koreans, Thais, Malays, Vietnamese, Laotians and Tibetans A 1998 study conducted by DE Hawkey showed dental morphology of the Sinhalese is closely related to those of the Austro-Asiatic populations of East and Northeast India 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

Skin pigmentation

In 2008 a study looked at SLC24A5 polymorphism which accounts for 25-40% of the skin complexion difference between Europeans and Africans and up to 30% of skin colour variation in South Asians The study found that the rs1426654 SNP of SLC24A5, which is fixed in European populations and found more commonly in light skinned individuals than dark skinned individuals 49% compared to 10%, has a frequency of 50-55% in the Sinhalese and 25-30% in Sri Lankan Tamils This allele could have arisen in the Sinhalese due to strong East Asian genetic admixture, further migration from North India or strong selection factors
