Re: Minimizing the genetic input of mediocre stock
Just a couple of thoughts. What about drone traps on the hives you do not want mating, this along with the green frames to keep the production of drones down in those colonies.
Second and most obvious to me. how about a breeding yard that does not contain undesirable colonies?
Say for example I produce 100 colonies for selection. of those 100 only the best 10 will be kept. Assume there is a selection criteria for now. From best to worst these 10 colonies are ranked from 1 to 10. which colonies are used for drone production?
Only those ten colonies will remain in my apiary. the others will be moved or sold. Only one will produce queens. 9 will produce drones to fertilize those queens.
IN mating the queen contributes two sets of genes. while each drone contributes one full set. if a queen mates with 20 drones the genetic pool is now 10% queen and 90% drone. but at the point of egg laying the queen is 50% of the genetics and an individual drone (only 1 sperm per egg) is only 2.5% of the genes. This results in a colony that is 50% genetically the queen and 50% genetically a combination of all 20 drones.
Because of this I see the method to maintaining genetic diversity while still selecting for traits is through the drones. for this reason hives 1 thru 9 are drone producers. and number ten, the worst is the queen producer. I may be making errors in my thinking but I see the fastest way to spread selected genes throughout my stock is via drones not queens.
