ELI5: When an animal species reaches critically low numbers, and we enact a breeding/repopulating program, is there a chance that the animals makeup will be permanently changed through inbreeding?

When the population gets so low, the genetic diversity is *definitely* reduced—no chance about it. This makes the species more susceptible to problems in the future even if the population comes roaring back. They are more likely to all die from the same disease, for instance. The genes are so similar that it is less likely for a few members of the population to have immunity.
