Where did that come from?
Are you even aware that you are mixing a number of concepts in your posts? You've jumbled mutation rates, epigenetic mutations, teratogenic mutations, and transmission fidelity (which is what I was speaking to) together as if they all have the same probabilities.
Don't be obtuse. Transmission fidelity applies to any mutation that is passed to another organism, and it does not reach a 100% expected or actual real-world statistical success rate.
