Suppose that in olden-times, only a handful of socially dominant kin networks were wealthy enough for education. And then social and education reform changed things so that a) everyone finished high-school, regardless of birth, and b) higher education resource allocation shifted to merit and motivation from social breeding. Suppose further, that the breakdown of the class system meant that idiosyncratic genetic markers of aristocratic inbreeding declined along with elite endogamy.

Would the results of this study be any different?
