Re: Getting queens - what does this mean to genetics?
Mated queens that you purchase have already proven to be layers. Once queens start to lay they never mate again. A mated buckfast queen will only produce buckfast bees.
Drones jump from colony to colony. Many people don't know this. I wouldn't necessarily worry about inbreeding in your area as there should be an adequate pool of viable mates. Queens have been successfully mating in the wild for thousands of years. The only way to guarantee your genetics is to purchase your queens from a reputable supplier. And actually this turns out sometimes to be no guarantee.
