Idk, I kinda like this decision. It may be frustrating to not know but, just like with Combee, this is firmly based on how this works in real life, like the only real important bees are female and only female bees can be queens, while many species of lizards very much have females as the dominant sex to the point that they sometimes don't need males to multiply. This kind of things just scratch that itch I have that was left in my brain by watching Animal Planet all the time as a kid.
