  • Fingerprints of 100 New Zealand-Samoan males and 93 females have been analyzed. Whorls are more numerous in fingerprint females (65.6%) than in males (55.6%). The index of pattern intensity displays a higher value in females (16.49) than in males (15.48). The bimanual differences both in males and females are not statistically significant for the occurrence of patterns on the digits of the right and left hands. Also the difference between both sexes for the occurrence of patterns is not statistically significant. Incidences of actual symmetry on homologous digits represented 78.2% in males and 85.8% in females. The mean total ridge counts showed $175.7{\pm}54.6$ ($M{\pm}SD$) in males and $171.6\{pm}49.8$ ($M{\pm}SD$) in females, respectively. Conclusively, this study shows that the New Zealand-Samoans are closely related to the Mongoloids in quantitative dermatoglyphics.

  • 한국인 2,925명 (남자:804, 여자:2,121)에 대하여 지문형과 pattern intensity index를 분석하였다. 지문형의 출현빈도는 남녀의 성차가 있었다. Whorls (남자:53.6%, 여자:45.7%)와 Radial loops (남자:2.9%, 여자:2.2%)는 남자에서 높이 나타났고, 반면 Archs (남자:1.9%, 여자:2.9%)와 Ulnar loops (남자:41.6%, 여자:49.2%)는 여자에서 출현빈도가 높았다. Pattern intensity index는 남자가 15.2가, 여자는 14.3으로 남자에서 높았다. Polygene model의 유전을 하는 양적 형질인 지문 총 융선수를 776명 (남자:426, 여자:250)에 대하여 계산한 결과 총 융선수는 남자가 140.4$\\pm$41.2로 여자의 129.8$\\pm$40.6보다 높았다. 지금까지 다른나라에서 보고된 총 융선수는 인종에 따라 121$\\sim$170으로 인종적 차가 있었다. 총 융선수와 지능지수와의 상관관계는 없었다(r=-0.0027, N=343).

  • Fingerprints of 114 Australian Aboriginal males and 90 females have been analyzed. Whorls are more frequent in males (56.7%) than in females (51.2%) and loops are less frequent in males (42.6%) than in females (47.0%). The index of pattern intensity displays a higher value in males (15.60) than in females (14.94). The bimanual differences both in males and females ave not statistically significant for the occurrence of patterns on the digits of the right and left hands. Also the difference between both sexes for the occurrence of patterns is not statistically significant. Incidences of actual symmetry on homologous digits represented 74.0% in males and 77.3% in females. The mean total ridge counts showed 156.65 $\pm$43.32 (M$\pmSD) in males and 148.6943.64 (M$\pmSD) in females, respectively. Conclusively, this study represents that the Australian Aborigines conform closely to the Polynesians in finger dermatoglyphics.

  • Fingerprints of 104 New Zealand Maori males and 98 females have been analyzed. Whorls are more abundant in females (55.0%) than in males(47.3%). The index of pattern intensity reveals a higher va1ue in females(15.39) than in males (14.52). The bimanual differences both in males and females are not statistically significant for the occurrence of pattern on the digits of the right and left hands. The difference between the sexes in occurrence of patterns is not statistically significant. Incidences of actual symmetry on the homologous digits represented a mean of 78.8% in all subjects. The mean total ridge counts showed 161.7 in females and 159.6 in males, respectively. Thus, the Maori show greater affinities with the Mongoloids in quantitative dermatoglyphics.
