Abstract: The normal values of 12 dermatoglyphic parameters of Buyi and Gelao Nationalities were reported. The total number of 450 samples was obtained from Buyi Nationality, and 410 froin Gelao Nationality. The 12 dermatoglyphic parameter values obtained from Buyi and Gelao Nationalities were as follows: 1. the frequencies of finger patterns A，, A% Lu? Lr, W9, Wd of Buyi Nationality 0.69%, 0.11 %, 45.03%, 2.01 %, 39.98%, 12.35%, and the Gelao Nationality 1.66%, 0.37%, 46.38%, 2.39%, 38.78%, 9.98% respectively; 2. mean total finger ridge count (TFRC): Buyi, 132.99, Gelao, 135.95； 3. mean a—b total ridge countt Buyi, 36.68, Gelao, 37.33； 4. mean atd angle: Buyi, 42.33°, Gelao, 42.43°; mean tPD: Buyi, 16.21 %, Gelao, 17.15%； 5, mean line index of transversality: Buyi, 2 3.69, Gelao, 24.34； 6. frequencies of true patterns of palmar thenar areas: Euyi, 3.24%, Gelaj, 4.41%； 7. frequencies of true patterns of palmar hypothenar areas: Buyi, 8.93%, Gelao, 8.70%; 8. frequencies of true patterns of palmar interdigital areas I2> I3, I4t Buyi, 0.89%, 65.86%, Gelao, 2.82%, 18.75% 9 65.04%； 9. frequencies of persons with simian line, palmar flexion crease of transitional I type, palmar flexion crease of transitional II type and Sydney type: Buyi, 3.13%, 7.82 %, 5.14 % , 0, Gela。，6、1 %, 9.05 %, 6.35%, 0.49%； 10. frequencies of hallucal patterns A, L, W: Buyi, 8.11%, 64.33%, 27.55%, Gelao, 10.25%, 61.58%, 28.17%； 11. frequencies of true patterns of sole interdigital areas L： Buyi, 7.67%, 63.22%, 13.44%, Gelao, 8.17%, 54.88 %, 8.66%; 12. frequency cE hypothenar true patterns of sole: Buyi, 1.78%, Gelao, 2.44%. The difference between sexes, left and right hand, and nationalities were analysed.
