[Southack]

"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.

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.

Sure it does. Surely you can imagine a single mutation which is passed on from one organism to one of its offspring.
