A Genetic Study of Four Population Groups of Uttara Kannada District of Karnataka
Four population groups, namely, Halakkis, Siddis, Gonds and Havyak Brahmins of Uttara Kannada district of Karnataka state of South India, have been studied for six serological, and red cell enzyme markers to find out genetic affinities of these population groups. In the ADA system, only Siddis showed the fast variant allele ADA*V with a frequency of 1.4 percent. To the best of the authors’ knowledge, this variant has not been reported from the po…

Genetic Affinities of the Siddis of South India
Historical records indicate that the Portuguese brought the African Siddis to Goa, India, as slaves about 500 years ago. Subsequently, the Siddis moved into the interior regions of the state of Karnataka, India, and have remained there ever since. Over time the Siddis have experienced considerable cultural changes because of their proximity to neighboring population groups. To understand the biological consequences of these changes, we studied th…
