I have heard that over time an aggressive queen's genes will be passed along, so that every successive generation will be more aggressive. My question is can it work the other way as well? Could an aggressive hive become more gentle if left alone? Reason why I ask is I have two very good queens head of two very strong hives, but man can they be tempermental sometimes. I hate to do away with them because apart from their distemper they are great queens/producers. Any thoughts on this?
