I'm not sure what you mean by "minor genetics (evolutionary) changes".
I'm going to assume that you mean mutations.

Well, the usual assumption is that a mutation happens in a single cell.
If a mutation happens in a single cell of an adult, it will probably
not do much for/to him. Well, if it happens in a type of cell that
divides frequently it may have some effect - it it happens in a white
blood cell it could conceivably confer immunity to AIDS, but more likely
will cause leukemia.

But whatever it does to the adult, it won't have an important evolutionary
impact unless it can be passed on to the children. And it can't. Unless,
that is, the mutation happens in a 'germ line' cell destined to become
a sperm or egg. That can be passed on. In fact, most mutations happen in
the parent before sex, rather than in the fertilized egg after sex. But
such mutations in the parent probably won't have much effect on the parent.
