You’re dangerously close to asking if Lamarckian evolution is correct, which was disproven in favor of darwinian. But I think youre asking something a little more nuanced, about whether affected DNA gets passed on. And that only happens if your sperm/egg is affected And is based solely on how the sperm/egg is affected. Otherwise dna changes stay local and don’t pass. So, you would never see any visible mutation passed on.
