The social supergene dates back to the speciation time of two Solenopsis fire ant species.

Scientific reports - 14 Jul 2020

Cohen Pnina, Privman Eyal

Abstract excerpt

Colony social organization of multiple Solenopsis fire ant species is determined by a supergene with two haplotypes SB and Sb, which are similar to X/Y sex chromosomes. The ancestral monogyne (single-queen) social form has been associated with homozygous SB/SB queens, while queens in colonies with the derived polygyne (multi-queen) social structure are heterozygous SB/Sb. By comparing 14 Solenopsis invicta...
