摘要:
目的:调查河南汉族人群19项遗传性状的分布特点并探讨其在法医学中的应用。方法:采用分层整群随机抽样方法调查河南汉族人群1 010个无关个体,对前额发际、发旋、发式、达尔文结节、耳垂、耳垢、眼睑、鼻尖、卷舌、翻舌、三叶舌和尖舌12项头面部遗传性状,拇指关节、中指被毛、小指弯曲、利手、扣手、交叉臂和叠腿7项躯干部遗传性状的分布情况进行分析。结果:19项遗传性状中,前额发际、达尔文结节、眼睑、尖舌、三叶舌和扣手6项在男女间分布的差异具有统计学意义(χ2=4.868、5.493、7.264、5.298、7.769和5.144,P均<0.05)。在1 010个河南汉族无关个体中,19项遗传性状构成的表型组合共有938种,其中仅出现1次的有885种(87.62%);匹配概率为0.001 2,个人识别率达0.998 8。结论:河南汉族人群中19项遗传性状的表型组合具有较高的遗传多态性,在法医学个人识别等应用中具有一定的意义。
Abstract:
Aim: To investigate the distribution characteristics of 19 hereditary characters in Han population of Henan Province and to assess its application in forensic genetics. Methods: Distribution characteristics of 12 head and facial hereditary characters including front form of hair, hair whorl, hairdo, Darwin nodules, ear lobe, cerumen, eye fold of the upper eyelid, nose top, retroflex,twisting tongue, trefoil tongue and tip of tongue,and 7 trunk hereditary characters including thumb joint, hair of middle finger, curl of little finger, handedness, cross arm, folding leg, and hand clasping of 1 010 unrelated individuals were investigated in Henan Han population by using stratified cluster random sampling method. Results: Six hereditary characters including hair forehead, Darwin nodules, eyelids, pointed tongue, trefoil tongue and hand clasping had significant difference between males and females (χ2=4.868,5.493,7.264,5.298,7.769 and 5.144,P<0.05). 938 types of combined phenotypes of 19 hereditary characters were observed among 1 010 unrelated individuals in Henan Han population. Out of them, 885(87.62%) types were found only once. Probability of match and power of discrimination were 0.001 2 and 0.998 8,respectively. Conclusion: Combined phenotypes of 19 human hereditary characters in Henan Han population has high genetic polymorphism which is helpful for individual identification in forensic practice.
