Rubbish experiments do not prove much.
As Steve Crook has pointed out, it is a basic truth of beekeeping that two hives side by side behave totally differently.
Most Queens mate with 10 plus random drones, 30 feet up in the air, miles away from the hives ( Whee!). So their genetics are always different and always unknown unless you do some weird Instrumental Insemination.
To do a decent piece of science on bees you need a very large sample and a lot of data.
I like bees and keep a number of hives, but doing research on them is not easy.
