Hi all.
Happy holidays to all.
Two brief points.
1.  I agree wholeheartedly with Murray.  His statement does not need
comments.
2.  I think that some of the contributors to this thread are/have missed
Garth point regarding genetic material exchange (or lack of it) by affected
drones.  Extending this thought a little further
affected queens will have a rough time getting up into the drone pools which
should make them available to affected drones.  The importance of this point
is that being that there is such a large population of drones in our bee
yards and hence in the drone pools,  the old reliable law of survival of the
fittest should prevail.  Only the drones whose respiratory ability is not
affected will mate with the queen be they in drone pools or outside of the
drone pools.  Food for thought when talking about acquired hereditary traits
in open spaces.  If we are talking about Artificial Insemination, then that
is an entirely different ball park because "factors" are controllable.
Best regards.
Happy Holidays to all.
