However, long-term inbreeding may cause problems to start showing up, so adding new genetic material into your breeding project is recommended (called Outcrossing). Generally if you Line Breed one generation, you will then want to consider Outcrossing the next generation.

Here's an older thread that touches on this subject: Line Breeding / Outcrossing
Hope this helps!
This is also my understanding. That it's not bad so long as you don't do it for too many generations. You would be OK to breed sire to child or sibling to sibling.
