目的: 研究山东潍坊汉族4 项人类群体遗传学特征。方法: 2011-07 在山东寿光采用随机整群抽样
方法调查了370 例( 男215 例,女155 例) 汉族的4 项人类群体遗传学指标。结果: ( 1) χ2 检验显示,山东潍坊汉
族拇指过伸率、环指长率、指甲扁形率均男性高于女性; ( 2) u 检验显示,在我国族群中山东潍坊汉族拇指过伸型
率很高,环指长率、指甲扁型率均较低; ( 3) 山东潍坊汉族与手足相关的4 项指标间无相关性。结论: 山东潍坊汉

on 4 human population genetic characters in Shouguang county of Shandong province. Results: χ2-
test shows that the hyperextension thumb, ring finger and flat nail of males are higher than that of females.
u-test shows that hyperextension thumb have high percentages in Chinese ethnic groups,but
there are low percentages in ring finger and flat nail. There are no correlations among 4 characters hand
