inbreeding

Question
what if someone mated brother and sister, what would be the "alot of problems" you were referring to?

Answer
Hi Sierra

It depends on the breed and the specific problems that are inherent in the lines.

Professor Steven Jones of the University College of London said "People are carrying out breeding which would be first of all entirely illegal in humans and secondly is absolutely insane from the point of view of the health of the animals"

You can see first hand what in-breeding can do on the BBC special entitled Pedigree Dogs Exposed.
