Study On The Morphology Of Palmer Dermatoglyphics Of Macaca Mulatta In The Taihang Mountains

Dermatoglyphics as a specific character which is controlled by the polygenes, is important in the morphologic study of primates. Many scholars have studyed the populations and sex differences, at the same time, they also have understood the pattern types, the distribution frequency and the PI between various patterns of Macaca mulatta's palm and plantar. In China, these were more studies about the metacarpal and metatarsal, the weight ratios and bone length ratios of Macaca mulatta, but sexual dimorphism and asymmetry of the pattern is little in Macaca mulatta. The distribution frequency of various patterns, the position of triradius, the difference of interspecific, the characteristic and distribution of whorls are the main contents of this paper, and in order to understand the differences of the sides and sex of Macaca mulatta's palm. All of those works can offer some evidence for morphologic study of primates, and hope to accumulate the useful and credible datas for the basic research such as heredity, heteromorphosis, evolution and classification etc. In this paper,72 cases dermatoglyphic specimens of Macaca mulatta in Taihang mountains (male 26 ,female 46 ) have been analysied. Age does not required. The pattern types and occurrence frequency of various dermatoglyphics were studied, the datas were analysied by SPSS 13.0.0 for Windows. Statistical methods were One-Way ANOVE and X2 test.The main conclusions and results are as follows:(1)The pattern types of palmerThere are O,L,Z,M and W 5 types of patterns on palmer, and the predominant patterns are L, Z and W.(2) The frequency of various patterns of palmerThere is no statistical significance between gender and side about the distribution frequency of the main patterns of palmer(P>0.05). The result of X2 test shows that there is significant sides differences(P<0.000)and no statistical significance sex differences(P>0.05). This kind of distributed characteristic had certain species-specific. The difference was mainly due to genetic factors, environmental factors also contributed to the bilateral differences. (3) The position of triradius on palmerThere were 8 triradius often appeared on the palmar in the Taihang Macaca mulatta, respectively is 1, 3, 4, 6, 7, 8, 9 and 10. The number of triradius was 8 to 11and the average number was 9.1. Both of them displayed that left side was bigger than the right, the male was bigger than the female. The average number of the left side was 9.3 and the right was 9.0, the male was 9.4 and the female was 9.0.
