TONGUE PIGMENTATION AMONG THE DHANGARS OF MAHARASHTRA AND GEORGIANS OF GEORGIA, USSR

The paper reports distribution of tongue pigmentation, an autosomal recessive character, among the Dhangars of Maharashtra and Georgians of USSR. Strikingly the trait is completely absent among the Georgians, while among the Dhangars it depicts a wide range of variation, 7.69% to 21.29%. The available data suggest that the trait decreases in the south-north direction in India and perhaps is confined to tropical areas of the world.
