Supergene Linked to Fire Ant Queen Development

A study from the University of Georgia suggests that a specific group of genes, known as a supergene, influences fire ant development. The research, published in the Proceedings of the Royal Society B, indicates that while nutrition and environment play major roles, carriers of this supergene are more likely to reach the larger sizes associated with queens.

Comprising over 500 tightly linked genes, the supergene is often found in colonies with multiple queens. Researchers utilized the chemical methoprene to mimic juvenile hormones during larval development, finding that while both carrier and non-carrier ants could reach similar sizes, supergene carriers were consistently overrepresented among the largest individuals.
