It’s not different, the two are tied. See my comments above, including my response to you related to epigenetic changes from stress.

The person you are responding to likely has notable epigenetic modifications that have lasted way past the initial negative environmental stimuli (in proportion to the trauma). It’s not a hopeless situation, there is literature on how to reverse and mitigate that, but it’s important to be aware of.

No. There's no proof that the gene activation differences that occur are negative. There's no proof that the gene activation differences are the cause of the psychological and behavioral differences seen by victims of trauma.
