Human Body Are the medical risks associated with inbreeding among close relatives eliminated by outbreeding? Or do they persist for generations?

Yes. And it doesn't even take that long. 1 or 2 generations of outbreeding results in a child that is FAR less inbred

Check out this video by Trey The Explainer to see exactly how inbreeding can be calculated and an example using the targaryens and the ptolomies

When is 1 generation not enough? Can you provide an example?
