【摘要】 采用Ｈｏｌｚｉｎｇｅｒ的改良遗传度计算法（ｈ￣２）和Ｖｏｇｅｌ等人的三种遗传度计算法（），对合肥市３０对同卵双生于（ｍｏｎｏｚｙｇｏｔｉｃｔｗｉｎｓ，ＭＺ）、３０对异卵双生于（ｄｉｚｙｇｏｔｉｃｔｗｉｎｓ，ＤＺ）和６０对条件基本相同的群体对照组（ｃｏｎｔｒｏｌｐａｉｒｓ，ＣＰ）做了智商（ｉｎｔｅｌｌｉｇｅｎｅｅｑｕｏｔｉｅｎｔ，ＩＱ）的遗传度（ｈｅｒｉｔａｂｉｌｉｔｙ）研究。结果证明儿童ＩＱ的遗传度：Ｈｏｌｚｉｎｇｅｒ法计算为０．６４３；ｖｏｇｅｌ的和三种方法计算分别是０．６４、５、０．８１２和０．３９７，三者平均是０．６１８。学龄前组的ＩＱ遗传度高于学龄组。提示采用Ｖｏｇｅｌ的三种计算方法对同一批样本进行计算，可以避免系统性误差，结果更为可靠。更多还原

【Abstract】 AbstractThe intelligence quotients (10) were measured in30 pairs of monozygotic twins, 30 pairs of dizygotictwins and 60 pairs of control, whose conditions werealmost the same, such as sex. age and parent’s educa-tion levels, etc. The Holzinger’s improved method ofheritability ofestimation ( )were used forthe analysis. The results showed that hzwas 0.643; 0.645: 0.397. The average of , andwas 0.618. Our results also showed that theheritability of IQ in preschool child group was higherthan that of school child group.更多还原
