Isn’t there a known phenomenon where a species has been inbreeding for so long that they’ve selected out defects caused by inbreeding via natural selection? I thought I had heard that about lab mice, but I can’t find info about it.

It'd be nice if it had, but it didn't. (I'm not sure why: perhaps lab mice have gone through far more generations, with much more stringent selection on overall health, and that is how much it takes to purge all the exposed bad recessives etc?)
