Supergenes are clusters of tightly linked loci maintained in specific allelic combinations to facilitate co-segregation of genes governing adaptive phenotypes. In species where strong selection potentially operates at different levels (e.g. eusocial Hymenoptera), positive selection acting within a population to maintain specific allelic combinations in supergenes may have unexpected consequences for some individuals, including the preservation of disadvantageous traits. The nuclear gene Gp-9 in… 
Asymmetric assortative mating and queen polyandry are linked to a supergene controlling ant social organization
TLDR
This study reveals that the supergene variants jointly affect social organization and multiple components of the mating system that alter the transmission of the variants and thus influence the dynamics of the system.
Evidence of Selective Mating and Triploidy Among Two Social Forms of Solenopsis invicta (Hymenoptera: Formicidae)
TLDR
This study examined the genotypes of queens and their stored sperm during a mating flight in Florida where polygyne colonies predominate, and provides evidence of non-random mating.
Simple inheritance, complex regulation: Supergene‐mediated fire ant queen polymorphism
TLDR
The distinctive supergene‐associated gene expression trajectories recorded at the onset of a queen’s reproductive life expand the known record of relevant molecular correlates of a complex social polymorphism and point to putative genetic factors underpinning the alternate social syndromes.
Unexpected patterns of segregation distortion at a selfish supergene in the fire ant Solenopsis invicta
TLDR
The data confirm the prediction that the Sb supergene in the fire ant Solenopsis invicta is a selfish genetic element capable of biasing its own transmission during reproduction, yet counterselection for suppressor loci evidently has produced an evolutionary stalemate in TRD between the variant homologous haplotypes on the “social chromosome”.
The dynamic relationship between polyandry and selfish genetic elements
  • N. Wedell
  • Biology, Medicine
    Philosophical Transactions of the Royal Society B: Biological Sciences
  • 2013
TLDR
A potent and dynamic interaction between SGEs and polyandry is revealed highlighting the potential to generate sexual selection and conflict, but also indicates that poly andry can promote harmony within the genome by undermining the spread of S GEs.
Chemical communication of queen supergene status in an ant
TLDR
It is demonstrated that the Sb element is required both for production of relevant chemical cues of queens and for expression of the behaviours of workers that collectively result in worker Sb discrimination in S. invicta.
A simple genetic basis for complex social behaviour mediates widespread gene expression differences
TLDR
Gene ontology analysis showed that SB/SB queens upregulate reproductive genes faster than SB/Sb queens, and results suggest that many genes in the supergene are involved in regulating social organization and queen phenotypes in fire ants.
No mate preference associated with the supergene controlling social organization in Alpine silver ants
TLDR
It is concluded that the pattern of asymmetric assortative mating documented from mature F. selysi colonies in the field is not caused by mate preferences or major genetic incompatibilities between social forms, and there is no evidence that disassortative mate preference contributes to the maintenance of polymorphism at this supergene controlling ant social organization.
Can patterns of chromosome inversions in Drosophila pseudoobscura predict polyandry across a geographical cline?
TLDR
Female isolines derived from populations of Drosophila pseudoobscura from three locations in North America are used to examine whether different female remating levels are associated with patterns of chromosome inversions, which may explain patterns of polyandry across the geographic range, but there is no strong relationship between female remates levels and specific karyotypes of the various isolines.
Exploring the regulatory role of behaviour and genome architecture in the socially polymorphic ant, Leptothorax acervorum
TLDR
This thesis shows that in the absence of worker aggression (enforcement), functionally monogynous queens continue to engage in highly aggressive interactions and, crucially, high colony skew was not affected and it is shown that low skew is not affected by aggressive worker enforcement in polygynous colonies.

Multilocus evolution in fire ants: effects of selection, gene flow and recombination.
  • K. Ross
  • Biology, Medicine

  • 1997
TLDR
Evidence is presented that selection acting independently on Pgm-3 and Gp-9, in conjunction with gene flow from the alternate, "monogyne" social form of this species, may explain the origin of disequilibrium between the two loci in polygyne fire ants.
Selective Male Mortality in the Red Imported Fire Ant, Solenopsis invicta
TLDR
The bb genotype, rather than an obligate, developmental lethal, was present in some queens and common in alates, workers, and brood, suggesting some frequency of multiple mating in polygyne populations of Solenopsis invicta.
Chromosomal rearrangements maintain a polymorphic supergene controlling butterfly mimicry
TLDR
The results indicate that allelic combinations at known wing-patterning loci have become locked together in a polymorphic rearrangement at the P locus, forming a supergene that acts as a simple switch between complex adaptive phenotypes found in sympatry.
Molecular Variation at a Candidate Gene Implicated in the Regulation of Fire Ant Social Behavior
TLDR
No single b-like residue is completely predictive of polygyne behavior and, thus, potentially causally involved in its expression, so naturally occurring variation at Gp-9 in fire ants is described, and several unique alleles bearing various combinations of b- like and B-like codons are found.
GENETIC ORIGIN OF MALE DIPLOIDY IN THE FIRE ANT, SOLENOPSIS INVICTA (HYMENOPTERA: FORMICIDAE), AND ITS EVOLUTIONARY SIGNIFICANCE
  • K. Ross, D. Fletcher
  • Biology, Medicine
    Evolution; international journal of organic evolution
  • 1985
TLDR
Three hypotheses are proposed, based on current knowledge of sex‐determining mechanisms in the Hymenoptera, to explain the loss of genetic diversity associated with high rates of diploid male production in S. invicta: allelic diversity was reduced during colonization of North America by a small founder group, genetic structuring of polygyne populations due to local inbreeding caused reduced allelic Diversity and/or increased homozygosity.
Phenotypic Basis of Reproductive Success in a Social Insect: Genetic and Social Determinants
TLDR
There is a counterintuitive relation between the potential and realized reproductive success of queens in multiple-queen societies of this ant, which is an unusual example of genotype-environment interaction in gene expression in which the environmental component is the social environment.
Colony genetic structure and queen mating frequency in fire ants of the subgenus Solenopsis (Hymenoptera: Formicidae)
TLDR
Fire ant colonies represent simple, albeit enormous, family groups, and single insemination and foundress parentage of males appear to be conserved reproductive traits in the subgenus Solenopsis, whereas another major determinant of colony genetic structure, the number of functional queens, is evolutionarily labile in this group.
Major gene effects on phenotype and fitness: the relative roles of Pgm‐3 and Gp‐9 in introduced populations of the fire ant Solenopsis invicta
TLDR
These analyses show that once the effect of Gp‐9 genotype is taken into account, Pgm‐3 genotype no longer is significantly associated with differences in queen phenotype or the probability of queens being accepted in polygyne colonies.
Ant Reproductive Strategies and Sex Allocation Theory
  • P. Nonacs
  • Biology
    The Quarterly Review of Biology
  • 1986
TLDR
An analysis of a wide body of literature on ants strongly supports the genetic relatedness hypothesis (GRH), and the bimodal sexual investment pattern appears to be a mixed "evolutionary stable strategy and state" and seems proximately determined by the amount of food resources.
Experimental Conversion of Colony Social Organization in Fire Ants (Solenopsis invicta): Worker Genotype Manipulation in the Absence of Queen Effects
TLDR
The results support the conclusion that polygyny in S. invicta is induced by a minimum frequency of colony workers carrying the b allele, and confirm that its expression is independent of queen genotype or history, worker genotypes at genes not linked to Gp-9, and colony genetic diversity.
