| 摘 要： | 目的：探讨双生子手肤纹类型特点以及遗传与环境因素对手纹的影响。方法：利用遗传流行病学方法研究济宁市区60对双生子的指纹纹型。结果：在41对同卵双生（MZ）子及19对异卵双生（DZ）子的各类指纹纹型中以斗型纹最常见,其次为尺箕,弓型纹、桡箕最少。指纹效型的遗传度为0．5506。总指嵴纹计数（TFRC）和绝对总指嵴纹数（AFRC）的遗传度分别为0．8316、0.7616。结论：指纹纹型及指纹嵴数主要受遗传因素的影响。

| Abstract: | objective:To explore the characteristics of fingerprint pattem and the effect of genetic and environment facters in twins. Methods: The fingerprint patterns of 60 twins were examined by means of genetic epidemiologic methods. Results: Among all the fingerprint patterns of 41 monozygotic twins and 19 dizygotic twins, the whorl pattern was most common, followed by the uluar loop,the arch and the radial loop. Heritability of fingerprint pattern, TFRC and AFRC were 0. 550 6, 0. 831 6 and 0 .761 6 respectively. Conclusions: The genetic factors have important effects on fingerprint pattern. |
