Moreover, it seems that some kind of competition among sperms may
exist inside the spermatheca, at least when AHB sperm is present:

I wouldn't choose "clone" to express the genetical relationship
between queen and drone, because this word can easily lead someone to
a misunderstanding. I'm not sure if the same occurs in other parts of
the world, but at least in Brazil, a lot of people believe that all
drones of the same queen are genetically identical. In fact, each
drone just inherits half of his mother's genes, but they are
"carried" by a random set of chromosomes, some (or all) of them
having been "crossed over" with their correspondent pairs during
meiosis, and that gives the queen a very low probability to generate
two identical drones along her life.
Best regards.
