Inbreeding has the same effect regardless of the species: It allows the breeder to double up on the genes controlling desirable traits. Unfortunately, it does the same for undesirable traits.As far as the other less rare breeds go, what are y'alls opinions on inbreeding? All this thinking about finding different bloodlines got me thinking, what are the adverse affects of inbreeding. From what I've read it seems that inbreeding, or "linebreeding" as they call, it is a neccessity to keep and/or eliminate certain traits. What do you guys think on the matter?
