Minor kink tail and breeding genetics question

[Sublimeballs]

Ok so as some of you know I got my female pure kalatoa SD retic last month and was waiting to get my unrelated male this month. Well I got him and noticed at the tip of his tail it's bent(other then that he's in perfect shape). I haven't been able to find out if this is from hatching or from injury. I plan on breeding these in the future and want opinions on wether or not others would breed him(for fear of potential genetic predisposition to kinks). The person I got them from is regareded as the best breeder of pure super dwarves, so idk what to think. Sorry for the crappy pic.
