“Handedness heritability was estimated to be 0.24–0.26 in large samples of 21,127 twin pairs [31] or samples consisting of twins and their siblings adding up to 54,270 individuals [32]. Similarly, Somers et al. [33] estimated the heritability of left-handedness to be around 0.24 from a genetic linkage study in human pedigrees”
