The royal british family, hundreds of years of inbreeding, lower iq??

I read the responses before I answered and I think some ppl are being a little snitty here! I think this is a very interesting question that has merit. It is true that there use to be alot of inbreeding in royal families. Not brother to sister but alot of cousins. How do you think the Romanovs were related to almost every royal house in Europe? Fat lot of good that did them. But it is also the reason that the boy had hemophilia (as did some other males of royal blood, there cases are not as famous though) and some of the royals have had other interesting diseases. At one time Queen Victoria grandchildren were king/queen of almost every European country. SOOO when their children grew up to marry someone deemed appropriate, they would probably be marring a cousin. This was happening for centuries though. In recent years of course this is no longer the norm.
