Abstract: Fire ants (Solenopsis invicta) are socially polymorphic, with some workers tolerating several queens in their colony and others tolerating just one; this study shows that a non-recombining supergene is responsible for this social polymorphism, and the operation of this genomic region is remarkably similar to that of sex chromosomes.
