It might also mean that a specific trait or quality within a group is 'bred out' to the point of virtual extinction. For instance, if there is a family in a fanfic with a special magical ability, but through intermarriage with other families without that ability and a lack of emphasis on maintaining it, the ability gradually disappears from the family line. This concept can be used to show how things can be lost over time in a fictional society.
Another way to look at it is in terms of a selective breeding process gone wrong. In the fanfic world, perhaps a powerful group was trying to breed a certain type of creature with enhanced abilities for their own purposes. But their breeding methods were so extreme that it led to the creature's overall health deteriorating and eventually the entire population being wiped out. This shows how hubris and unethical practices in a fictional context can have disastrous consequences.
