Detailed explanation-1: -Children of left-handed parents are more likely to be left-handed than are children of right-handed parents. However, because the overall chance of being left-handed is relatively low, most children of left-handed parents are right-handed.
Detailed explanation-2: -Special or not, lefties are born, not made: Genetics are at least partially responsible for handedness. Up until last year, it was assumed that hand preference comes from asymmetrical genes in the brain-two hands, two brain hemispheres, one is dominant.
Detailed explanation-3: -This suggests links between handedness and language during human development and evolution. One implicated gene is NME7, which also affects placement of the visceral organs (heart, liver, etc.) on the left to right body axis-a possible connection between brain and body asymmetries in embryonic development.
