I think left handedness isn't genetically inherited, I thin it a comfort factor signalled from the brain in early childhood development.

There are many right handed parents for instance who have noticed that all their children are left handed.

So in these instances it cannot possibly be genetic
 
researches have proved that a child decides which and to use(left or right) while in the womb
