The obtained results do not support a major gene for body mass index in chinese, the discrepancies between our study and previous studies may result from ethnic difference between chinese and other populations ; the general model provides the best fit to the data, while the environmental model is the second parsimonious model, perhaps due to complex mode of body mass index inheritance ; a moderate heritability estimate is found for body mass index ( h2 = 0. 313 ), lower than that of other populations, this is presumably due to the fact that aside from the influence of genetic bases, body mass index is strongly influenced by environmental factors and that there is a low proportion of obese individuals in samples ( only 4. 1 % individuals have body mass index > 30 )

    分離分析的結果表明, ( 1 )體重指數不存在主基因分離,不同於在其他非中國人群中檢測的結果,說明存在種群差異性; ( 2 )一般模型提供了最合適模型,環境模型是次之的嚴格模型,可能由於體重指數遺傳模式的復雜性所致; ( 3 )中國人群中體重指數具有適中的遺傳率( h ~ 2 = 0 . 313 ) ,低於其他人群中的結果,這是由於體重指數除了受遺傳因素影響外還受環境因素影響及樣本中低比例的肥胖個體( 4 . 1的個體bmi 30 )的原因。
