phenotypes. While classical supergenes—governing traits such as wing patterns in …

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 …

Genomic evidence suggests the balanced lethal system in Triturus newts originated in an instantaneous speciation event

J France, M de Visser, JW Arntzen, W Babik… - BioRxiv, 2024 - biorxiv.org
The balanced lethal system found in crested and marbled newts of the genus Triturus
presents an intriguing mystery. All adults possess two distinct forms of their largest …

AG Tafreshi, SP Otto… - … Transactions of the …, 2022 - royalsocietypublishing.org
Supergenes often have multiple phenotypic effects, including unexpected detrimental ones,
because recombination suppression maintains associations among co-adapted alleles but …

Locally adaptive inversions in structured populations

C Mackintosh, MF Scott, M Reuter, A Pomiankowski - Genetics, 2024 - academic.oup.com
