湖南侗族左扣手人群的手纹分析

目的　对湖南侗族左扣手人群的手纹分布特点进行研究 ,积累侗族群体遗传学与民族学资料。方法　用油墨拓印法捺印手纹 ,放大镜下观察分析。结果　侗族左扣手人的指纹分型特点是 :尺箕 >简斗 >双箕斗 >桡箕 >简弓 >帐弓 ;Ws型在各手指的出现率、掌褶纹类型的百分率、以及总指纹嵴数和a -b纹嵴线数存在明显的性差 (P <0 0 5或P <0 0 1) ;女性Ws和Lu的出现率、男性Ws和Wd在各指的分布 ,以及通贯型掌褶纹百分率与对照组存在明显差异 (P <0 0 5或P <0 0 1)。结论　湖南侗族左扣手人的斗型纹与掌褶纹的分布具有一定的特异性

Analysis of Dactylogram in Left-Hand Clasping People of Dong Nationality in Hunan

Objective To accumulate the material on colony genetics and ethnology, the distribution of dactylogram in left hand clasping people of Dong nationality in Hunan provice was studies. Method Printing the dactylogram with ink, and observing it by magnifier.Results Each type of dactylogram in number on left hand clasping people of Dong nationality was as follows: Lu(ulnar loop)>Ws(simple whorl)>Wd(double whorl)>Lr(radial loop)>As(simple arch)>At(tented arch). Percentage of simple whorl in different fingers, percentage of different palmar flexion crease, TFRC and a bRC were obvious differences between male and female (P<0 05 or P<0 01). Percentage of simple whorl and ulnar loop on female, percentage of simple whorl and double whorl on each finger of male, and percentage of simian line were obvious difference between left hand clasping people and right-hand clasping people (P<0 05 or P<0 01). Conclusion The distribution of whorl and palmar flexion crease in left-hand clasping people of Dong nationality in Hunan provice was qualified for distinctiveness.
