摘　　要：采用Slater区分单基因和多基因遗传的计算模式及Smith无偏分析方法对21个家系资料的分析表明:利手、优势足、扣手特征均为常染色体单基因显性遗传,R型为显性性状。虽然环境因素对这类特征的表现也有一定的影响,但遗传因素仍起主要作用。The data of 21 families were analyzed by the method of Slater's calculating model to differentiate between single-ene and multi-gene heredity and by the method of non deviation analysis. The results showed that the hereditary mode of handedness or preferential foot or hand-lasping is the dominant heredity of single gene of auto-some, and the right type of all of them is the dominant character. In a way, although environmental factors affected the phenotypes of these characters,hereditary factors were also the decisive ones.
