[The mutation is passed on, just like AS said. It has the same chance of changing again as it did before, but has a much higher chance to be passed on. Elementary biology you are disputing.
Which is why redheaded people have mostly redheaded kids.
Except, they don't.
The mutation has the same chance of being passed on, not a higher chance.
"The proportion of mutated DNA copies shifts rapidly and unpredictably from mother to child making it very hard to predict what proportion of mutated DNA will be passed on."
