摘要/Abstract

摘要： 对贵州布依族、仫佬族和毛南族1239例的9对遗传性状的基因频率进行了调查, 并对民族间基因频率差异进行显著性检验。结果显示: 卷舌和小指弯曲的显性基因频率高于隐性基因频率, 而叠舌、前额发际、发旋、耵聍、拇指类型、中指毛、环食指长则相反; 卷舌、叠舌、前额发际、耵聍、拇指类型、环食指长的基因频率在民族间差异较大, 而发旋、中指毛、小指弯曲则相对较小。

Abstract: This paper focuses on the comparison of gene frequencies of nine characters reported in the Buyei, Mulam and Maonan nationalities living in Guizhou. The results of this survey are summarized briefly as follows: 1) the dominant gene frequencies of these characters (piled-up tongue, forehead hair edge, hair whirl, cerumen, thumb type, middle finger hair, and ring and index finger length) were less than that of their recessive genes, but the opposite observation was true for two other characters (rolled-up tongue and little finger curve); 2) among the different nationalities, the difference in gene frequencies of rolled-up and piled-up tongue, forehead hair edge, cerumen, thumb type, and ring and index finger length was quite significant, followed by hair whirl, middle finger hair, and little finger curve.
