摘要
本文调查了455个家庭的卷舌和非卷舌系谱,还调查了3311人的卷舌和非卷舌的频率。利用Snyder群体遗传比率,证明了人类卷舌和非卷舌的遗传为一对常染色体基因所决定,卷舌基因对非卷舌基因为完全显性。
In this paper, it is proved with the results of the investigation on the tongue-rolling and-unrolling pedigrees of 455 families and on the tongue-rolling and-unrolling rates of 3311 individuals and with Snyder Population Heredity Rate that human tongue-rolling and-unrolling heredity is controlled by a pair of autosome genes and the tongue-rolling gene is completely dominant to the unrolling one.
