Many C57BL/6J inbred mice were tested for paw preference. In unbiased worlds, approximately 10 percent exhibited lateral preferences inconsistent with the world bias, and males were more strongly lateralized. Influences of world bias appear to be superimposed upon an already laterally dichotomized population. Initial left-right sense, it is posited, arises as an outcome of a seemingly random process.
许多C57BL/6J近交系小鼠接受了爪偏好测试。在无偏差的情况下，约10%的小鼠表现出与环境偏差不一致的侧向偏好，且雄性小鼠的侧向化程度更强。环境偏差的影响似乎叠加在一个已经侧向二分的群体之上。据推测，最初的左右感觉是一个看似随机的过程的结果。
