Supergenes as drivers of ant evolutionM. Chapuisat, Myrmecological News, 33:1-18. 2023.
Ants show striking diversity in social organization, raising major questions on the proximate and ultimate causes of such variation. The shift from one-queen (= monogyne) societies to multi-queen (= polygyne) societies has long been viewed as a phenotypically plastic response to ... |

Cryptic recessive lethality of a supergene controlling social organization in antsP. Blacher, O. De Gasperin, G. Grasso, S. Sarton-Lohéac, R. Allemann and M. Chapuisat, Molecular Ecology, 2022.
Supergenes are clusters of linked loci that control complex phenotypes, such as alternate forms of social organization in ants. Explaining the long-term maintenance of supergenes is challenging, particularly when the derived haplotype lacks homozygous lethality and causes gene ... |

Maternal effect killing by a supergene controlling ant social organizationA. Avril, J. Purcell, S. Béniguel and M. Chapuisat, Proceedings of the National Academy of Sciences, 2020.
Supergenes are clusters of linked loci producing complex alternative phenotypes. In a series of experiments, we demonstrate that a supergene controlling ant social organization distorts Mendel’s laws to enhance its transmission to adult offspring. One supergene haplotype is ... |
