Bloodlines & Banjos!

Sacred lineage, bloodlines and secret ruling elites get some great mileage on the forum, but one thing puzzles me! When we peasants get involved in such activities that lead to a depleted gene pool and subsequent physical and mental defects.

So...given that there so few of the 'chosen ones' to procreate and preserve their sacred bloodline, how do they manage to keep a viable breeding population?
We all know that 'they' supposedly marry outside the family from time to time, but surely that wouldnt be enough to keep things ticking over for thousands of years and still have a recognisable heir at the end?

The 'Beast of Glamis' may well be a case of things coming back to bite them on the ass, but you would expect there to be so many more cases ?
