Maternal effect killing by a supergene controlling ant social organization

A Avril, J Purcell, S Béniguel… - Proceedings of the …, 2020 - National Acad Sciences
Supergenes underlie striking polymorphisms in nature, yet the evolutionary mechanisms by
which they arise and persist remain enigmatic. These clusters of linked loci can spread in …

development by either genetic factors, environmental cues or a combination thereof. Ants …

Supergenes as drivers of ant evolution

M Chapuisat - Myrmecological News, 2023 - biotaxa.org
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 …

Cryptic recessive lethality of a supergene controlling social organization in ants

P Blacher, O De Gasperin, G Grasso… - Molecular …, 2023 - Wiley Online Library
Supergenes are clusters of linked loci that control complex phenotypes, such as alternative
forms of social organization in ants. Explaining the long‐term maintenance of supergenes is …
