Simple inheritance, complex regulation: Supergene-mediated fire ant queen polymorphism.

Molecular ecology - 1 Oct 2020

Arsenault Samuel V, King Joanie T, Kay Sasha, Lacy Kip D, Ross Kenneth G, Hunt Brendan G

Abstract excerpt

The fire ant Solenopsis invicta exists in two alternate social forms: monogyne nests contain a single reproductive queen and polygyne nests contain multiple reproductive queens. This colony-level social polymorphism corresponds with individual differences in queen physiology, queen dispersal patterns and worker discrimination behaviours, all evidently regulated by an inversion-based supergene that spans more than...
