[Study on 4 human population genetic characters of Mongol and Han in Western inner Mongolia].
From 1998 to 2001, a sample of 2760 Mongol and Han individuals was investigated in 3 areas (Eerduosi city, Xilinguole and Bayannaoer leagues) from Inner Mongolia. Each individual was studied on 4 genetic characters (thumb type, palmar digital formular, fingernail type and plantar digital formular). The result is as follows: (1) The frequencies of the straight thumb were over 60%, and there were no significant sexual differences in all of 6 groups. (2) The frequencies of the ring-finger-longer were much higher in 6 groups, and there were significant sexual differences in 4 groups. (3) The frequencies of the long-shaped fingernail were the highest in all groups, the squat-shaped were the lowest. (4) The big toes were longer than the second toes in most people of 6 groups,but without significant sexual differences in each groups. (5) There were no significant correlations between 4 characters.
