Social chromosome variants differentially affect queen determination and the survival of workers in the fire ant Solenopsis invicta.

Molecular ecology - 1 Oct 2014

Buechel Séverine D, Wurm Yanick, Keller Laurent

Abstract excerpt

Intraspecific variation in social organization is common, yet the underlying causes are rarely known. An exception is the fire ant Solenopsis invicta in which the existence of two distinct forms of social colony organization is under the control of the two variants of a pair of social chromosomes, SB and Sb. Colonies containing exclusively SB/SB workers accept only one single queen and she must be SB/SB. By...
