The basis of right- vs. left-hand-use preference in humans has been debated for a long time. Culturally learned, birth stress, and biologically specified causes are the prominent etiologies under consideration. A 2003 (Klar 2003) study reported a correlation between a person's preferred hand and the scalp hair-whorl orientation developed on the head. By reinterpreting results of a 1927 (Schwarzburg 1927) study on the genetics of the hair-whorl trait, support for a recent single gene, two-allele "random-recessive model" for both hair-whorl orientation and handedness trait inheritance is demonstrated.
人类使用右手还是左手的偏好基础长期以来一直存在争议。文化习得、出生压力和生物学特定原因是目前考虑的主要病因。2003年(克拉尔,2003年)的一项研究报告称,一个人的惯用手与头上长出的头皮发旋方向之间存在关联。通过重新解读1927年(施瓦茨堡,1927年)一项关于发旋性状遗传学的研究结果,证明了最近关于发旋方向和利手性状遗传的单基因、双等位基因“随机隐性模型”。
