Haha, I doubt so that would happen with skills per se, though things like the form and size of the hand, how slender your fingers are and things like that actually are. In my case, my younger siblings inherited my mom's slender and long fingers, and they can actually do 10 and 11 note intervals on the piano with relative ease o_o On contrast I inherited my dad's regular hands with slightly fat fingers, and 9 note intervals are the most I can do regularly, while I could do 10ths with some stretching, and 11ths were out of my reach
