Is being left or right handed inherited or genetic?!


Question: There are quite a few people in my family that are left-handed, but they are ALL on my maternal grandmothers side, my son is left-handed, my husband and myself are both right. Just curious. ( our daughter is right-handed )
Our son showed a preferance for his left hand as an infant. It was hard to teach him simple things like tieing his shoelaces, holding eating utensils correctly, etc.
It really is a right-handed world.
