Abstract: This paper investigates gene frequencies of ear lobe type, hair vortex, hand clasping, dimple presence, and handedness of 111 (54 male and 57 female) college students belonging to the Miao nationality in Guizhou. The results showed that the recessive gene frequency of ear lobe type was greater than the dominant, and the distribution of hair vortex in males and females differed significantly (P<0.01). Handedness was also relatively significant among the five genetic traits tested in this population, but other traits had no significant relationship (P>0.05). Gene frequency differences clearly exist between the Guizhou Miao and other nationalities or areas in China.
