河南汉族人群中19项遗传性状特征的分布及法医学应用价值
Distribution of 19 hereditary characters in Henan Han population and its forensic application value
摘要
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 he-reditary characters including front form of hair , hair whorl, hairdo, Darwin nodules, ear lobe, cerumen, eye fold of the up-per 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 un-related individuals were investigated in Henan Han population by using stratified cluster random sampling method .Re-sults: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 dis-crimination 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 .关键词
