I was speaking of beekeepers not breeding their own queens.  See the paper I
cited recently in the post "'Kin Selection' Crops Up Again".  The paper
concludes that workers play a larger role in the genetics that get passed on
via queens and drones than we might have suspected, and might need to be
overtly culled or included breeding programs.

But wasn't the "Bond Method" admitted as failing to make a significant
tangible difference in practical queen selection and breeding?

".we emphasize that what we demonstrate in the Bond bees is only a relative
mite tolerance, yielding a slower mite population build up compared to
colonies where mite control has been practiced".

(In other words, "survivors" were not showing sufficient mite resistance as
compared to selected-for-traits stock.)

and

"However, the higher survivability rate of colonies from selected strains
could not be correlated to differences in the relative natural mite
mortality (mite mortality/1000 bees), the number of damaged mites in the
natural mite fall, hygienic behavior (pin-killed brood test), or the
infertility rate of Varroa in worker brood."

(The statement above being an acknowledgement that the surviving colonies in
"Bond" programs survived by mere luck alone, and had no traits of measurable
tangible value in a breeding, exposing the subjective valuation of "higher
colony strength" as, at best "optimistic", and at worst "confirmation bias".
