I think I know where the "seven generations" comes from.

I have a friend who breeds show dogs. She told me that, if you breed in a
dominant trait, such as a certain color or other trait, it takes seven
generations of careful breeding to eliminate that particular trait. This is
were the DNA comes in, and unless DNA is damaged in some way, as by
radiation, for instance, then a trait is not going to be passed on.
