I actually know a bit about genetics, but your assertion that you can't achieve something because of your genetics has me wondering how much you know about genetics.
Genetic predisposition doesn't mean what you think it means. You seem to think it means that if your dad didn't throw 90+ you are incapable of it, but you are forgetting that you are not your dad, that would be a clone. The reason your dad may not have thrown 90+ might be a weakness in his shoulder...but your mom's side of the family may have better shoulders, thereby eliminating that weakness from your gene pool.
Genetic predisposition means if your dad DID have the capability to do something you are likely to be able to do the same thing. It does NOT mean if he couldn't do something you for sure can't do it either, that's the beauty of genetics! It can pull strengths from both parents into one child and the next child may have pulled all the weaknesses. Traits that make our bodies work more efficiently are usually more dominant, but there is no guarantee the special ability will be passed down.
There is also the argument of nature vs. nurture. Can person X throw 90+ because his genes give him a special type of shoulder/elbow? Or can person X throw 90+ because over the course of the last 10 years he slowly built up the muscles through repetition needed to achieve the velocity? Was it nature, meaning genetics, or was it how you nurtured your body to behave the way you wanted?
It's not natural to hold your bat with your knuckles lined up...that's not in anyone's genetic make-up, however, every time you are at bat do you even think of how to line up your knuckles? No, it's second NATURE to you that that is how you hold your bat. My point is the body can be trained to do things that go beyond genetics.
Work hard, best of luck!
