Well my two patternless are in no way related, and I have babies with kinked tails. I know many other breeders with unrelated pairs who have the same thing in their patties. I have out crossed them many times and it still results in kinks. So, who knows, maybe we are just unlucky here in BC.

Ghosts exhibit faded coloration and even the black spots are dull. They appear to be in constant shed their whole lives.
