You're awesome. That's a really good point. Bees are weird. A queen has 32 chromosomes but a male results from an unfertilized egg and has only 16
chromosomes (a drone). Apparently this has no problem itself with bees. In the case of the different species, I'm pretty sure that the number of
chromosomes is the same for all species of bee. I tried to look it up on the net, but I couldn't find the chromosome numbers for those two different
species. I think that the Africanized/killer bees are more different in terms of behavior, and not form, than the European ones because they are a
subspecies. They are both honey bees, which were relatively recently one species. It takes a long time and many more mutations for the chromosome
number itself to change. So no, the offspring would not be sterile, I don't think. I also don't think that they would breed. Bees are very
territorial and typically remain isolated to their colonies. It would be a big deal for one to move to a different hive, and a bigger deal for it to
move to one of a different type of bee.
But I did read in one or two of the articles that another "stress factor" thought to contribute to the immune problems is inbreeding among colonies
and populations. Although not directly responsible, it could play a part in the puzzle.
There is only one species that we use for commercial crops and move around to pollenate different things. They interact the most and are the species
that is exhibiting CCD that I know of. I'm not sure if other bees are, but I think it is just this type of honeybee. Africanized bees are not
typically used for commercial purposes so they would not have interacted with the honeybees. Whereas many beekeepers will bring their colonies all
around the world to famous places like the lavender fields in France. I think this is where something contagious would play a factor, and also where
colonies may switch up a bit. I'm really not sure, though.
The type of bee that we use is the European honey bee, Apis mellifera. Wikipedia sites a number of bees like Africanized bees as subspecies, which
probably wouldn't cross subspecies. I think only mellifera gets CCD and I believe that there aren't populations of mixed bees. I could be wrong, but
it's not common.
