With good reason, I think. A late friend married his first cousin and the way genetics work (Google the pea experiment), he and his son had identical DNA. His daughter, younger, did not. He had a couple of charts, which certainly overlapped exactly but not being a biologist, I don't know what that meant. Mother nature works in curious ways.
