Excellent post, I would only add that the change may not be permanent.
Varroa can go from resistant to susceptible and back again. It is not
just one way.

One of the discoveries of the human genome project was that they still
do not know how many genes we have since many of the sequences have no
apparent use. But sometime in the past they may have had importance.
