Dr Adam Rutherford and Dr Hannah Fry ponder what determines left or right handedness, and why are there so few lefties? Adam consults handedness expert Professor Chris McManus from University College London. He's been trying to track down the genes responsible for whether we're right or left handed.

First broadcast on The Curious Cases of Rutherford & Fry, 3 October 2016.
