Variation in social behaviour is common, yet little is known about the genetics underpinning its evolution. The >40,000 species of ants and bees present unique opportunities to investigate this.
We discovered that alternate supergene variants carried by a pair of “social chromosomes” determine whether a fire ant colony accepts exactly one or up to hundreds of queens. Surprisingly, similar social polymorphism and underlying supergene architectures convergently evolved multiple times. Many questions remain about such regions, but detailed analyses are infeasible with traditional Illumina data.
This project will use long-molecule sequencing (Nanopore/Sequel/Irys) to examine the birth and evolution of social supergenes.
