Leg-crossing refers to the preferential tendency for individuals to sit with one leg crossed over the other. In this study about 62% of the population are right leg-crossers, 26% are left leg-crossers, and the remaining 12% report that they have no preference or are indifferent. Familial data suggest that leg-crossing may be under genetic control: although the data do not fit any straightforward recessive or dominant Mendelian model, they are compatible with the type of model invoking fluctuating asymmetry which has been used to explain the inheritance of handedness, hand-clasping and arm-folding.
交叉腿是指个体倾向于将一条腿交叉放在另一条腿上的偏好。在这项研究中，约62%的人习惯右腿在上交叉腿，26%的人习惯左腿在上交叉腿，其余12%的人表示没有偏好或无所谓。家族数据表明，交叉腿可能受基因控制：尽管这些数据不符合任何简单的隐性或显性孟德尔模型，但它们与用于解释利手、扣手和抱臂遗传的波动不对称模型类型相符。
