Handedness displays a complex inheritance pattern. For example, if both parents of a child are left-handed, there is a 26% chance of that child being left-handed. [23] A large study of twins from 25,732 families by Medland et al. (2006) indicates that the heritability of handedness is roughly 24%. [24]
If the parents are both right-handed, in dizygotic and monozygotic twins there is a 21% chance of one being left-handed.

Left-handers who were forced during childhood to use their right hand showed a larger surface area of the central sulcus in their left hemisphere, which is associated with right-handedness. Also, structures in the basal ganglia such as the putamen also mirrored developmental right-hand dominant individuals in the forced group.
