摘要
目的:探讨贵州彝族、白族群体部分遗传性状出现率分布及其特征间的相关关系。方法:采用群体遗传学公认的方法,调查了879人(彝族472人、白族407人)8对群体遗传学性状,使用SPSS13.0统计软件包进行民族间、性别间以及两两特征间相关性的统计学处理。结果:贵州彝族翻舌、卷舌、唇厚、下颏类型、利手、拇指类型、中指毛、小指弯曲8对遗传性状显性出现率分别为56.8%、8.3%、11.7%、58.1%、86.2%、39.0%、56.4%、53.0%;白族则分别为62.4%、8.8%、15.0%、50.9%、91.2%、44.5%、60.4%、49.6%。结论:①贵州彝族、白族群体在下颏类型和利手2对性状间存在显著性差异(P<0.05)。②彝族卷舌男女间存在显著性差异,白族拇指类型男女间存在显著性差异(P<0.05)。③8项群体遗传学特征间相关性较小。
Aim:To study the distributive frequencies and it's corelations of 8 population genetic traits in Yi and Bai nationalities in Guizhou province. Methods: According to the techniques of human population genetics and cluster random sampling,a survey on 8 genetic characters of 879 cases(Yi nationality 472 and Bai nationality 407) was carried out in October 2008,and then dealt with data using SPSS 13.0 software.Results: The distributive frequencies of 8 population genetic traits in Yi nationality were 56.8%,8.3%,11.7%,58.1%,86.2%,39.0%,56.4%,53.0% respectively;Those of Bai nationality were 62.4%,8.8%,15.0%,50.9%,91.2%,44.5%,60.4%,49.6% respectively.Conclusion: There are significant differences(P<0.05) between Yi and Bai nationalities on 2 genetic characters(chin type and handedness);and significant differences(P<0.05)on Curly Sides of Tongue in sex in Yi nationality,significant difference(P<0.05)on Thumb Style in sex in Bai nationality;There are few corelations on 8 population genetical Traits of Yi and Bai nationalities in Guizhou province.
