Open Question: left handed and ambidextrous genes?




   Hello, well I'm basically 15, and I am learning about genes in science, and I chose to do it on like the right and left side of your brains, and how the right side controls the left and the left controls the right.
I am confused on the left handed gene and ambidextrous, I chose to do this project because I myself am ambidextrous, my Great grand dad was ambidextrous and he was the only ambidextrous or left handed in the family, he was also amazingly intelligent, he knew everything, seriously its scary, he was so intelligent he could invent things and he built parts or planes in the world war 2, and nower days we found his diary recently and my nan was thinking of publishing it because it is so amazing.
..anyway back to where I was,
is this left handed/ambidextrous gene why he was so clever? could that gene of just being able to write with both hands be something to do with intelligent..? -  I have taken after him with the ambidextrous gene,
what causes someone to be ambidextrous, how do their brains work if they can use both?
I'm so interested and I find it cool lol!
