I think it can go either way. A lot of kids come off as if they feel like they are entitled to become a doctor just because their parents are....this would be a huge red flag for adcomms, especially if they think they don't have to do the stuff that all other premeds need to do to get in (volunteer, etc). My dad is a doctor, and he said that if you don't have all the EC's and stuff they will probably look at you and think your parents are pushing you into it (definitely not true in my case...since he always said he never wanted any of his children to become doctors because he knows the sacrifices). So definitely try and demonstrate why it is that YOU want to go into medicine, and not rely much on your parents. However, like Catalystik said, you do have the advantage of knowing a little more what it is like lifestyle-wise, coming from the prospective of a family member. I mentioned knowing full well the sacrifices and hard work it will take to achieve my goal because I saw how hard my dad worked, and experienced him not being home ever. But, I did also take the opportunity to shadow other specialties, and see medicine from that side too.
