Is there really inbreds in the Ozark mountains or anywhere in the world?

Answer 1

There are some people in the Ozark mountains who have married 5th cousins. In fact, it is quite common in many places. The closest to inbreeding occurs in the Arab world where marriage between first cousins is common. Historically, the closest inbreeding occurred among Egyptian, Incan, and Polynesian royalty where a brother would marry a sister.
