More proof that genetics is not read-only.

No, this doesn't permanently alter the DNA sequence.

Doesn't matter. It's the "reflections on trusting trust" kind of thing - we, our parents, grandparents, etc. form a chain; some runtime modifications to replication mechanism could propagate forward indefinitely, without changing the DNA in the process.

Nice insight. To save a few clicks to those remembering this classic (or reading for the first time!):

But, it is like commenting out regions in code. You are factually right, in that there is no editing of the DNA sequence i.e. no mutations. But this phenomenon exerts a similar end effect.

Not "end", exactly - at least, not if you look past N generations.

The question is, how many generations does it take for this to wear off? Or is it "good until cancelled"?
