Genetic studies on Sinhalese

[1] 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.

[6][7] 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).

[8] 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.

[9] 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.

[7] 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.

[9] 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.

[18] 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.
