Cool, with your enthusiasm, I would bet you will be raising queens within a year. You enjoy the bees, grafting, raising your own queens is tempting and rewarding.
As far as genetics are concerned, I did not mention due to the fact a beek can always make a queenless split from a hive with desired traits providing eggs or larva from a desired queen to the split. The bees would raise the queen for you.
The ultimate to selecting for genetic traits is II. Poland is the II capital of the world generating over 10,000 II queens a year from 500 trained beeks as portrayed in American Bee Journal just a few months ago. Out of the 500 trained beeks, only 50 were considered very good with only FIVE, 5, being commercial quality. Five beeks in the whole country, that is not very many considering Poland is the II capitol of the world and most likely the single most govt back/supported bee industry of any country. In Poland bees are considered important as cattle in the US, II QUEENS are registered with the state.
