[Lindale]

I have noticed that some of the Elves are inbreds... look at Celebrian, whose mother Galadriel is a descendant of Olwe, and whose husband Celeborn is akin to Elwe, Olwe's brother. Another example, Aragorn and Arwen. They are both descended from Earendil, their (fore)fathers being Elros and Elrond.

Now in biology I read that inbreeding in some species actually retains the nice traits of whatever you're breeding (example, you want only pink bougainvillea, don't let it cross-pollinate with other colors). But inbreeding also makes the risk of genetic diseases greater--this is very evident in breeding animals.

So why don't the Elves get a little wacko with all their inbreeding? And Eldarion too?
