Not quite right. As I remember from 32 years ago, the trait has a
high rate of back mutation and the wild type is a better (more
effective) competitor. So if you maintain a very large population
for a long time, it will likely become dominated by normal
individuals after a while. But for us with small populations, it is
easy to select artificially against any winged flies that arise, and
for us, it is hard to tell a back mutation from a contaminant.
