I'm taking heat because the idea is so contrary to popular belief. They crucified Jesus too y'know

My immediate words following the 'apples' statement was 'Their genes are 100% combination of you and your partners'.
Sensing some sarcastic disbelief but short answer is yes. To get a bit philosophical even if it's been somehow proven that life is 100% deterministic but you still don't know what happens next it should, for the most part, not affect how you go about your daily life. What this means for parenting is you can kick aside all extracurricular crap like Taekwondo, 3 other sports, and private school tuitions.
Anecdotally I've seen this play out over and over again. In-laws were booksmart libertarian parents who were completely hands off and let kids do their thing without any guidance or help. Their kids all have advanced degrees including an ivy leaguer on full ride scholarship. On the other hand you see rich people who made a fortune in real estate (every dumb rich guy ever) thru lucky idiot phenomenon struggle to help their dumb kids thru private school.
