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:[3]
Statistical Method Bengali Tamil North Western
Point Estimate 57.49% 42.5% -
Maximum Likelihood Method 88.07% - -
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.[1]
This is further substantiated by a VNTR study, which found 70-82% of Sinhalese genes to originate from Bengali admixture:[4]
Parenteral population Bengali Tamil Gujarati Punjabi
Using Tamil and Bengali as parenteral population 70.03% 29.97% -
Using Tamil, Bengali and Gujarati as parenteral population 71.82% 16.38% 11.82%
Using Bengali, Gujarati and Punjabi as parenteral population 82.09% - 15.39% 2.52%
D1S80 allele frequency (A popular allele for genetic fingerprinting) is also similar between the Sinhalese and Bengalis, suggesting the two groups are closely related.[5] The Sinhalese also have similar frequencies of the allele MTHFR 677T (13%) to West Bengalis (17%).[6][7]
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.[8] Also in the same test 24.1% of the subjects were R2 positive as subclades of Haplogroup P (92R7).[8] Haplogroup R2 is also found in a considerable percentage among Bengali of India. Sample size used was 87 subjects.

A study in 2007 found similar frequencies of the allele HLA-A*02 in sinhalese (7.4%) and North Indian subjects (6.7%). HLA-A*02 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.[9]
