河北三民族人群单双重睑遗传规律初探

The initial exploration on the heredity of single-double eyelid of 3 nationalities in Hebei

人类眼的单、双睑发生率有明显的种族差异。本文调查了河北省三个民族共 5 96人 ,双重睑者 32 7人 ,占 5 4.9% ,单重睑者 2 41人 ,占 40 4% ,一单一双 2 8人 ,占 4 6 % ,上述三种依次如下 :汉族 :共 2 92人中 ,三种分别 5 2 7%、41 4%、5 .82 % ;蒙族 :共 135人 ,三种分别 30 .4%、6 3 .7%、5 .9% ;回族共 16 9人 ,三种分别为 78%、2 0 %、2 % ,(P <0 .0 1)。基因频率 :单重睑、双重睑基因频率 ,汉族分别 :a =0 .6 434,A =0 .2 5 11;蒙族分别 :a =0 .7981,A =0 .2 0 19;回族分别 :a =0 .44 72 ,A =0 .5 5 2 8、三民族间有显著差异。

Upper eyelid type has a marked difference in the different race population,which is considered as the important sign on the study of human genetics.The distribution and heredity of singledouble eyelid among the population of Mengohu,Han and Muslim is unheard of report.We conducted analysis about the genetic heredity of the subject by surveying some college students from Hebei.
