What causes left- or right-handedness?

1 Answer

Answer :

The first reason why people are either left handed or left handed is mostly genetic.Experts assert that the left or right handedness is connected with ones biological genes and I think this one will be difficult to correct since it comes from within . Majority of people are right handed because the D gene in the body of each individual supersede and that helps to make the right hand more powerful than the left though the reverse is the case for left handed people because it seems their left does better than the right. Apart from genetic factor I think some people just decided to be left handed because I have a cousin that just love working with his left hand and he is now used to it.
