I am curious. It is my understanding that drones do not necessarily stay in the hive that they came from. So when doing A.I. how can the breeder be sure of the genetics of the offspring?

Separate bee yards. Some breeders go so far as to do it on an island.

That's true: Drones fly as far as 15-16 miles away.

There are multiple options:

1) Mark every newborn drone;
2) At start in the season use a queenseparator at the bodem: other drones can not enter the hive. Then, you need to build a flying cage (where drones cannot escape) for above of the hive (use f.e. a queen separator at one side of the cage: the bees can fly out buyt the drones can't). Every day (after the born of the drone), you can let them fly in the cage.

Problem solved.
