@dauderess It's not that simple, no. There are different types of mutations that can occur at any time and any place along the gene. You might find a common gene that's susceptible to degradation, but predicting the way that codons within the specific gene are going to be affected by a mutation is impossible. It could be a deletion of four base-pairs from that gene in one individual, it could be an insertion of three new base pairs in another. The thing in both of these types of mutations is that the addition or deletion changes how the gene is expressed. What once coded for proline-leucine-methionine could now code for proline-methionine-valine. Again, we can say after the fact what effect this can have, but you couldn't possibly predict where a mutation will occur in a given individual, nor could you necessarily protect against it; at least not with current technology. Ultimately, there is far too much genetic variation which arises in response to a whole host of environmental, genetic and phenotypic factors that we simply cannot make predict where or when a mutation will occur...at least not yet.
