Résumé
The frequency distribution of digital dermatoglyphic patterns was studied in 50 muslim families from Lakshmipur district from Assam. The study revealed asymmetry in the distribution of various patterns on individual digits though bimannual differences were not present. The mean pattern intensify index was found to be 13.54 + 3.76 corresponding to the presence of more number of loops and whorls in the data. Heritability, as calculated from mid parent child regression was found to be 82% indicating the presence of stronger genetic component in the formation of dermatoglyphic patterns. There was significant inter-familial variance suggesting the presence of genetic and environmental factors. The higher values of intra-familial variance also indicate influence of polygenes with additive effects on dermatoglyphic patterns.
