That's what MZ twins are - clones. Compare r(mz) and r(dz) - double the
difference to estimate h^2. I know of no twin study that estimated h^2 for
stock car racing, but we have h^2 for many personality traits. The fact that
h^2 >0 in all cases makes it reasonable to infer (not deduce) that h^2 for
stock car racing and other facets of thrill seeking have a heritability
greater than 0.
