I don't see much claw leaf on your plant, but as far as I know clawing isn't genetic. Typically is has something to do with the roots and watering. Too much water (and thus not enough oxygen for roots), rootbound, ph issue, something along those lines. Unless it gets really bad it is not a huge deal though. My plants had clawleaf for a while, I upped the PH from 6.4ish to 6.7ish and they liked that a lot better.
