How chromosomal inversions reorient the evolutionary process

EL Berdan, NH Barton, R Butlin… - Journal of …, 2023 - Wiley Online Library
Inversions are structural mutations that reverse the sequence of a chromosome segment
and reduce the effective rate of recombination in the heterozygous state. They play a major …

Sheltering of deleterious mutations explains the stepwise extension of recombination suppression on sex chromosomes and other supergenes

P Jay, E Tezenas, A Véber, T Giraud - PLoS biology, 2022 - journals.plos.org
Many organisms have sex chromosomes with large nonrecombining regions that have
expanded stepwise, generating “evolutionary strata” of differentiation. The reasons for this …

Genetic variation for adaptive traits is associated with polymorphic inversions in Littorina saxatilis

EL Koch, HE Morales, J Larsson, AM Westram… - Evolution …, 2021 - academic.oup.com
Chromosomal inversions have long been recognized for their role in local adaptation. By

The adaptive significance of chromosomal inversion polymorphisms in Drosophila melanogaster

M Kapun, T Flatt - Molecular ecology, 2019 - Wiley Online Library

The interplay of local adaptation and gene flow may lead to the formation of supergenes

P Jay, TG Aubier, M Joron - Molecular Ecology, 2024 - Wiley Online Library
Supergenes are genetic architectures resulting in the segregation of alternative
combinations of alleles underlying complex phenotypes. The co‐segregation of alleles at …
