Your heritage,your parents,your ancestory. I am left-handed and only 13% of the world is left handed.

Not exactly sure...but I'm a lefty and so is my brother and both of my parents. I have four sons. Two of them are identical (mirrored) twins. One is left handed, one is right handed (their hair even parts on opposite sides). I read once in a twins book that there is a very high rate of identical twins in utero (1st trimester) that result in only a singleton pregnancy....as one is absorbed or not viable and that that's where lefties come from.

The preference of handedness is an inherited trait.
