For workers to lay unfertilized eggs is to clone themselves, like drone layers which most are. This sure is a good trait for those needing drones in off season fwiw.........Now for workers to lay fertilized egges is good too, and a great back up system. and intercastes have been written about going back decades.......but how to trigger and use them!!! Actually nothing hard.......and yet seen early on in ALL races/strains looked at. So is thelytoky intercastes? or done by simple trigger(s) that happen from time to time, then man simple replicates by setting up simple triggers.
