How about this question... How probable would it be to artificially INDUCE a small population of blind cave fish to start growing eyes again without breeding it back to the parent Mexican Tetra line? Could it be done in less than 100 generations?
You read the Wikipedia article: it described an experiment in which the lens from a sighted Astyanax mexicanus was implanted into the blind cave form of the fish, and the fish developed a complete eye. That's not saying, of course, that the blind fish regained vision, and it certainly does not imply that its offspring would be sighted, but it suggests that the genetic information for building eyes is quite present.
Not sure if this just confuses the topic, but that is, after all, my speciality.
