Tongue pigmentation has been studied for testing the probable genetic mechanism determining this character. One pedigree from Kerala, and data on 132 families from West Bengal, have been reported here. Tests for segregation in the families support the genetic hypothesis that tongue pigmentation is an autosomal recessive character governed by two allelic genes, the ‘normal’ one being dominant over the ‘pigmented’. Detailed analysis of more data along with photographs of tongue pigmentation will shortly be published.
