Inbreeding a Lande's theoretical work contributed to the listing of the northern spotted owl as a threatened species in the United States.This can result in a loss of genetic variation and a higher prevalence of certain traits among the population.In the case of the Amish population who migrated from Europe to the United States, their small population size and limited gene pool due to inbreeding resulted in a higher prevalence of the genetic trait of polydactyly.Seeing themselves as special, there was a tendency for royals to only marry other royals. But there was only a certain number of royal families out there. With such a small gene pool, inbreeding was inevitable. By the 1800s it was said that every royal in Europe was mentally ill. And certainly that every royal family was an inbred family.
