Genetics is only part of the equation. Being your father's son in no way even guarantees you'll be like you're father. As you get older, you'll become more independent. When you graduate from high school and head off on your own, you'll be in an environment where you aren't constantly exposed to your family, or even your usual group of friends depending on what you end up doing.
It is an excellent opportunity to reinvent yourself and become the person you want to be.
