> Simply take a cordovan queen and II her with cordovan sperm and the next day II with WT sperm. Then count the % cordovan workers she produces versus time
As a pilot, I question this suggested methodology, as it lacks a clear and compelling form of shaking - wind turbulence when flying.
The test has to include some serious vibration after insemination, as this is what the queen would experience in natural mating.
At the scale of a bee, a tiny gust of wind can flip the bee over completely - I see this often for bees on approach to hive entrances on windy days.
An easier test would be the variation in color one can find on many brood frames. Nurse bees, all about the same age, all tending brood, are not at all consistent in color for hives of darker (Carni) color that have superseded and mated a queen with whatever mongrel Italian bees she could find. This mix of workers doing the same task seems fairly good evidence in contradiction to the "layered spermatheca" claim.
The quote "only fully mixing after many months (Koeniger and Koeniger)." Is most likely from the book "Mating Biology of Honey Bees", by Gudrun Koeniger, Nikolaus Koeniger, Jamie Ellis, and Larry Connor. I don't have a copy of that book, I'm guessing.
