There are too many examples of people from the same family, including identical twins, who had some many different outcomes in life. While DNA may play a role in helping mold us, the other thing called life has an incredibly stronger bearing on what makes us us including parenting and social interaction and schooling etc….
On the other hand, there are far too many examples of identical twins adopted by different families that even ended up in the same profession and even chose similar spouses to be ignored, It's frustrating that many people intentionally conflate eugenics (which called for sterilization or worse for people deemed "inferior") with simple acknowledgement that humans, like every other organism on the planet, have genes which influence their traits including behavior.
