Genetic study has been done, and even Harappadna.org have samples from Sinhalese Sri Lankas and Tamil Sri Lankans.
According to a
genetic admixture study by Dr. Gautam K. Kshatriya in 1995, the Sri Lankan Tamil are closely related to the
Sinhalese who are closely related to
Indian Tamils. Kshatriya found the Sri Lankan Tamils to have a greater contribution from the Sinhalese of Sri Lanka (55.20% +/- 9.47) while the Sinhalese had the greatest contribution from
South Indian Tamils (69.86% +/- 0.61), followed by
Bengalis from the
Northeast India (25.41% +/- 0.51). With both the Sri Lankan Tamils and Sinhalese in the island sharing a common gene pool of 55%. They are farthest from the indigenous
Veddahs.

Genetic 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:

A
genetic distance analysis by Dr Robet Kirk also concluded that the modern Sinhalese are most closely related to the Bengalis.
[3]
This is further substantiated by a
VNTR study, which found 82% of Sinhalese genes to originate from Bengali admixture:

D1S80 allele frequency (A popular allele for genetic fingerprinting) is also similar between the Sinhalese and Bengalis, suggesting the two groups are closely related.
[6] The Sinhalese also have similar frequencies of the allele
MTHFR 677T (13%) to West Bengalis (17%).

These findings are compatible with the historical chronicles the
Mahavamsa and
Dipavamsa. Which describe a Vanga prince (
Prince Vijaya)from 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 distrcit 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 either borrowed or.

I don't know which part of my comment you can't understand here. Also I wonder why most non-Sri Lankan PDF memebers here are trying to be experts about us.
