Due to the high rate of recombination of the honey bee, a drone is likely
to carry a new allelic combination, rather than a "copy" of either of the
chromosomes in the queen's genome.

Aye, but there's the rub. Recombination isn't much use if the parents are virtually identical, as in the case of a highly inbred cross. Otherwise, you wouldn't get the phenomenon of diploid drones* arising from worker eggs, a sure sign that inbreeding has occurred.

* This is where the larvae gets a copy of queen and drone chromosomes but they have the same alleles on the sex determination locus, causing the bee to grow into a male rather than a female. THESE are the true inbred drones, and are seriously messed up. The bees eat them as soon as they are born. However, Jerzy Woyke was able to mature them in the lab, as I recall
