MZ(同卵双胞胎)、DZ(异卵双胞胎)和单卵双胞胎中左撇子(L)的发生率是相同的。在MZ双胞胎中,R-R、R- l和L-L (R,右撇子)对的比例不呈二项分布。双胞胎没有受到任何特殊因素的影响,因此适合进行遗传分析。
The incidence of left-handedness (L) is the same in MZ (monozygotic) human twins, DZ (dizygotic) twins and singletons. The proportions of R-R, R-L and L-L (R, right-handedness) pairs in MZ twins are not in a binomial distribution. Twins were not subject to any special factors modifying their handedness and are thus suitable for genetic analysis.
