ELI5: When species get brought back from the brink of extinction there has to be a lot of inbreeding. How high is the risk that mutated features will change or derail the species?

Mutations occur randomly, but if one had a mutation it would become more prevalent in the population as a whole. That being said if it survived the extinction event long enough to breed it's unlikely that the mutation would seriously effect the species. The bigger problem would be a lack of genetic diversity. The species would be much more vulnerable to certain forms of diseases because they wouldn't be dissimilar enough to provide an effective buffer of immune individuals if a disease outbreak took place. This is actually a problem with cheetahs, they have trouble with viral infections because genetically they aren't very diverse.
