The royal wedding and outbreeding

By Razib Khan | April 29, 2011 2:14 pm

In the wake of the post from earlier this week on the inbreeding within the House of Windsor (and current lack thereof), Luke Jostins, a subject of the British monarch, has a nice informative post up, Inbreeding, Genetic Disease and the Royal Wedding. This tidbit is of particular interest:

In fact, eleventh cousins is a pretty low degree of relatedness, by the standard of these things. A study of inbreeding in European populations found that couples from the UK are, on average, as genetically related as 6th cousins (the study looked at inbreeding in Scots, and in children of one Orkadian and one non-Orkadian. No English people, but I would be very suprised if we differed significantly). 6th cousins share about 0.006% of their DNA, and thus have about a 0.06% chance of developing a genetic disease via a common ancestor. Giving that the Royal Family are better than most at genealogy, we can probably conclude that the royal couple are less closely related than the average UK couple, and thus their children are less likely than most to suffer from a genetic disease. Good news for them, bad news for geneticists, perhaps?
