      Brilliant question!! And I didn’t know the answer to that at all …. but it seems that Scientists can explain only 25% of “right handedness” by genes alone. As for the others, they have looked at dyslexia and discovered the PCSK6 which, along with other genes, controls the compartmentalisation of the brain controlling language. For most people, language ability is controlled by the left side of the brain and motor skills, such as handedness, are controlled by the right side. However, in left-handed people, it seems the sides are reversed….
      The question is though, is left-handedness suppressed in a way to skew the figures? Instruments (e.g. guitars) tools, computers, golf clubs and more, are set up for right -handed people?
