摘要
目的探讨贵州彝族、白族部分遗传性状分布及其特征间的相关性。方法采用群体遗传学公认方法,调查了879人(彝族472人,白族407人)6对性状,采用SPSS13.0统计软件包进行数据处理。结果贵州彝族前额发际、发质、眼睑、睫毛、耵聍和达尔文结节显性性状出现率分别为20.6%、34.3%、74.4%、76.3%、25.4%和60.8%;白族则分别为17.2%、39.3%、64.9%、86.2%、15.5%和66.8%。两民族眼睑、睫毛和耵聍3对性状均有极显著性差异(P<0.01),性别间发质有显著性差异(P<0.05或P<0.01);彝族男女间耵聍和达尔文结节有显著性差异(P<0.05)。结论贵州两民族群体多为非尖型前额发际、软性发质、双眼皮、长睫毛、干型耵聍和有达尔文结节,6项群体遗传学特征间有一定的相关性。
Objective To study distributive frequencies and the corelation among 6 genetical traits in Yi and Bai ethnic groups in Guizhou province. Methods According to the techniques of human population genetics and cluster random sampling, a survey on 6 genetical characters of 879 cases （ Yi ethnic group 472 and Bai ethnic group 407） was carried out in October 2008, then dealt with data using SPSS13.0 software. Results The distributive frequencies in 6 dominant traits of Yi ethnic group are 20. 6% ,34. 3% ,74. 4% ,76. 3% ,25.4% and 60. 8% respectively; Those of Bai ethnic group are 17.2%, 39. 3%, 64. 9%, 86. 2%, 15.5% and 66. 8% respectively. There are very significant differences （P 〈 0. 01 ） between Yi and Bai ethnic groups on 3 genetical characters （eyelid, eyelash and cerumen） ; and significant differences（P 〈0. 05 or P 〈0. 01 ）on hair metter in sex in two ethnic groups ; and significant difference （ P 〈 0. 05 ） on two genetical characters （ cerumen and Darwinian point） in sex in Bai ethnic group. Conclusion There are most people having the following characters ： fiat form of front hair, flexible hair matter, double eyelid, long eyelash, dry cerumen, having Darwinian point and a few eorelations on 6 population genetical traits in two ethnic groups in Guizhou province.
