Mutation, on the other hand ... makes your child, look nothing like you.
Generally not. Hundreds of mutation take place between every generation and the next. All the time. Most of these mutations don't 'do anything' of
any consequence. Occasionally a mutation will make the individual
who carries that mutated gene unviable, either killing it before it can
breed, or making it less successful at breeding. Occasionally a mutation will make the individual
who carries that mutated gene more successful
than its generational siblings who do not carry the mutation.
Sometimes those many many mutated genes that don't 'do anything' stay in the gene pool for many generations not doing anything, and then an
environmental change suddenly makes it useful.
It is very seldom that a mutation, harmful or not, makes your child look radically different to you - at least more different than we are used to.
Sure, once in a while, it does happen, but it is very very rare. Those tradgedies are no reason to 'fear' mutation. It is not something to be afraid
of, it is just something that is, and you can't do anything about anymore than you can stop the tides.
Perhaps the 'fear' comes from the fear of birth defects that are caused by toxins like radiation, cigarette smoke, or powerful drugs damaging large
sections of DNA, not changing a little bit here or there. Such environmental damage to the DNA is not 'mutation', that is gamete poisoning. Of
course such environmental damage may present itself as a harmless mutation, or a tragic defect. That is certainly something to fear.
