Female beetles are known to prefer males with bigger mandibles. In an experiment, a population of these beetles were picked and divided into two groups. For one group, only those males who had larger than average mandible size were allowed to mate to produce next-generation offspring (group 1). For the other group, the males and females were allowed to mate randomly (group 2). These populations were maintained using
