回顾了关于惯用手和大脑优势遗传的实验数据和理论工作。构建了两个基因、四个等位基因模型，一个基因座与左半球或右半球优势有关，另一个基因座与相对于优势半球的对侧或同侧手部控制有关。它与有关该问题的所有定量信息非常一致。提出并讨论了旨在解释相关定性事实的改进。
Experimental data and theoretical work on the inheritance of handedness and cerebral dominance are reviewed. A two-gene, four-allele model, one locus pertaining to left or right hemispheric dominance and the other to contralateral or ipsilateral hand control relative to the dominant hemisphere, is constructed. It is in excellent agreement with all quantitative information regarding this problem. Refinements designed to explain relevant qualitative facts are proposed and discussed.
