pink convicts are from line breeding for the most part, not inbreeding, if it was inbreeding they would wind up sterile and die off........ now line breeding and inbreeding are very close to each other.
Pink cons are leucistic, Line-bred to reduce all pigment. This is a gene mutation but im not sure how the breeders go about mutating the gene. Could be inbreeding. The gene is passed along though.
I avoid inbreeding because I find it extremely creepy when another creature is getting freaky-deeky with his sister 5 feet away from me.
