The fire ant social chromosome supergene variant Sb shows low diversity but high divergence from SB.

Molecular ecology - 1 Jun 2017

Abstract excerpt

Variation in social behaviour is common, yet little is known about the genetic architectures underpinning its evolution. A rare exception is in the fire ant Solenopsis invicta: Alternative variants of a supergene region determine whether a colony will have exactly one or up to dozens of queens. The two variants of this region are carried by a pair of 'social chromosomes', SB and Sb, which resemble a pair of sex...
